Feline Flashcards
Acetaminophin toxicity
cats are unable to process acetaminophen because of deficiencies int he liver’s ability to glucuronidate the drug into a form that can be excreted by the body. When the liver’s enzyme pathways for glucuronidation is saturated, the drug is broken down into a toxic metabolite called NAPQI that damages hemoglobin and red blood cells and liver cells. This can lead to fatal methemoglobinemia followed by acute liver damage (Heinz bodies and glossy brown color of the blood). Although liver failure and life-threatening methemoglobinemia are the two primary processes that occur, some cats may develop renal failure from nephrotoxicity. Renal failure occurs more infrequently, however.
Acute cholangiohepatitis
usually seen in younger cats (3-3.5 years) and is more common in males than in females. Likely to be depressed, dehydrated, and febrile. Neutrophilia with or without left shift. Mild increase in bilirubin and ALP common, with more severe elevations of ALT. Treatment includes antibiotics with aerobic and anaerobic coverage that are excreted unchanged in the bile (tetracyclines, ampicillin, amoxicillin, erythromycin, chloramphenicol, and metronidazole). Ursodeoxycholic acid is useful in all types of inflammatory liver disease because of its anti-inflammatory and anti-fibrotic properties on the liver. It also increases fluidity of biliary secretions. 50% survival.
Acute Glaucoma
Very painful condition characterized by epiphora, episcleral injection, corneal edema, and sometimes mydriasis.
Aelurostrongylus abstrusus
feline lungworm, treat with ivermectin and fenbendazole
Amylase
Hydrolyzes starches: Enzyme produced by the pancreas and also found in saliva that is responsible for digestion of starch or carbohydrates.
Amyloidosis familial disorder affects ____ breeds. Clinical signs are associated with ____ and ___ failure, while ____ may be secondary to glomerulotubular disease. Diagnosis is via biopsy and ____ stain but often not done due to the high risk of hemorrhage.
Abyssinian (kidney), Siamese and Oriental (liver) shorthair. Amyloid deposition occurs most frequently in the kidney and liver. Clinical signs in Abyssinian are typically those of chronic renal failure. Hypertension may be secondary to glomerulotubular disease. Biopsy and stain with congo red definitive but often not necessary due to high risk of hemorrhage. Manage symptoms and do not breed from these cats.
Anterior uveitis
Rubiosis iridis, aqueous flare, hyphema, hypopyon, keratic precipitates, and decreased intraocular pressure are all suggestive of anterior uveitis which an be caused by a number of infectious, immune-mediated, traumatic, and idiopathic causes.
Arginine deficiency
Arginine is an essential amino acid in cats used to make ornithine, which binds to ammonia that is formed from the catabolism of protein. Deficiency results in build up of ammonia and signs similar to hepatic encephalopathy
Black widow spider bite
Clinical presentation: found in basement recumbent and vocalizing, very rigid with muscle spasms
Toxin binds calcium channels, increasing membrane permeability and enhancing depolarization. Ascending motor paralysis and destruction of peripheral nerve endings occur. A single bit may be serious to adult humans and could kill a small animal. Clinical signs occur almost immediately with pain, due in part to the release of acetylcholine, which stimulates contraction of major muscle groups. There may be ascending motor paralysis, muscle spasms, muscle rigidity, and salivation. Death from respiratory or cardiovascular failure is possible.
Calicivirus
acute presentation of marked upper respiratory signs as well as oral ulcerations +/- conjunctival chemosis, and edematous lesions of the skin on the head and limbs. outbreaks of highly virulent and often lethal strains have been seen.
Capillaria aerophila
lungworm, parasite of the frontal sinus, trachea, bronchi, and rarely nasal cavity.
Cate bite abscess
Anaerobes most frequently isolated bacteria in cat bit abscesses. These include obligate anaerobes such as Fusobacterium spp., Bacteroides spp., and Clostridium spp. as well as facultative anaerobes such as Pasteurella spp. and Actinmyces spp. Treatment by establishing drainage, vet still choose to treat with antibiotics (Clindamycin or amoxicillin with clavulanate)
Chlamydophila felis is a ____ pathogen. The characteristic lesion is severe ____. The drug class of choice for treatment is ____
Chlamydophila felis is a respiratory pathogen. The characteristic lesion is severe chemosis. The drug class of choice is tetracyclines.
Cholangiohepatitis
Inflammation of the biliary system and liver parenchyma. Can be autoimmune in nature, or may be triggered by underlying infection or neoplasia. Concurrent disease often includes pancreatitis and inflammatory bowel disease.
Treatment: for non-suppurative cholangiohepatitis is prednisolone since it is most often immune in origin. Ursodiol is often used for its immunomodulatory, hepatoprotectant, and antifibrotic effects.It helps with the flow of bile through the liver. Other helpful therapies include S-adenosylmethionene (SAMe) and Vitamin E.
Chronic cholangiohepatitis
occurs in older cats (mean age 9 years)
Chronic kidney failure management
Restrict dietary protein (decreases formation of nitrogenous wastes and help to palliate hyperphosphatemia), phosphate binders (prevent absorption of phosphorus from the intestines), H2 blockers (decrease gastric acid secretion to help prevent vomiting and formation of gastric ulcers), Calcium channel blockers like amlodipine (palliate hypertension)
Cobalamin deficiency
causes inappetence, lethargy, and failure to thrive
Common congenital defect of white cats with blue eyes
deaf
Corneal dermoid
congenital
Cryptococcus neoformans
yeast-like fungus which has narrow based budding. Clinical signs: respiratory, central nervous system, eyes and skin are usually areas you will see affected. Most have nasal involvement characterized by facial swelling, distortion ‘roman nose’, chronic snuffling and discharge, and granulomatous masses seen coming out of the nostril.
Treat with Itraconazole
Diagnosis: serology is very useful, latex agglutination on serum, CFS, or urine. Visible yeasts surrounded by a large capsuleoccasionallyy seen.
Cryptosporidium
A coccidian that invades the small intestinal villi after ingestion of infected oocysts. It can be diagnosed with PRC. It is treated with clindamycin, azithromycin, or tylosin most commonly. It is usually an opportunist, so evaluation for underlying disease is appropriate.
Cuterebra
Fly that lays its eggs on soil or plants. The eggs stick to the animal’s fur when they come into contact. The eggs hatch and the larvae either penetrate the skin, are ingested when the animal grooms; or they enter the animal’s body through a natural opening, such as the nose. In most cases, the larvae migrate to areas just under the skin on the head, neck, or trunk of the animal. In dogs, cats, and ferrets, who are not the usually hosts of this parasite, the larvae may also migrate to the brain, eye, eyelids, or throat. As the larva grows under the skin, it produces a nodule or swelling.A small opening develops in the skin, through which is breathes. A small amount of drainage may occur around this breathing hole. The treatment is to incise the skin if needed to remove the larva. You have to make sure to remove the larva in whole and not crush it. If it is damaged or crushed, it can cause an anaphylactic reaction.
cytauxzoon felis is transmitted by _____, cats show clinical signs ____ after infection and these include a charateristic scleral _____, marked ____, icterus or pallor, an anemia associated ____ and thrombocytopenia. This organism lives in ____ as well as
Cytauxzoon felis is trasmitted by ticks, Cats usually show clinical signs 1-3 weeks after infection. Signs can include a characteristic scleral hemorrhage, marked pyrexia, icterus or pallor, an anemia-associated heart murmur and thrombocytopenia. This organism lives in the red blood cells as well as reticuloendothelial cells of the lungs, spleen, liver, lymph nodes. Cranial organomegaly can often be present. The bone marrow can be affected causing pancytopenias. Thrombocytopenia is likely related to the development of DIC. There is no effective therapy and prognosis is poor to grave.
Demodex cati
long slender mite which lives in the hair follicles
Diagnose on deep skin scrape
Treat with lime sulfur dip
Demodex gatoi
short and stubby mite which lives superficially. It is considered contagious to other cats and causes pruritus
Diagnose on superficial skin scrape
Treat with weekly lime sulfur dip
Dermatophytosis
characteristically causes pruritis, crusting, and often affect the head, neck, and ears.
Diagnosis of Feline Exocrine Pancreatic Insufficiency
Measure serum fTLI concentration
Dirofilaria immitis
Heartworm; adulticide dangerous - manage with preds and heartguard
Elastase
Peptidase that breaks down proteins and peptides.
The 3 subtypes of Feline Eosinophilic granuloma complex and their typical location are:
- Collangeolytic granuloma aka eosinophilic granuloma; round or linear raised ulcerative and nodular lesion, not pruritic, located on nose, chin, oral cavity or caudal thigh
2) eosinophilic plaque, located on abdomen and medial thighs, single or multiple raised, red, ulcerative lesions that ARE pruritic
3) eosinophilic ulcer aka indolent ulcer located on the upper lip with central area of pink to yellow tissue and raised edges
Estrus
typically lasts about 7 days (usually between 4-10 days)
Exocrine Pancreatic Insufficiency
Occurs when 90% of pancreatic exocrine function is destroyed. fTLI concentration is measured from a fasted blood sample and a trypsinogen level less than 8ug/L is diagnostic. Typically cats with EPI also have a concurrent chronic pancreatitis as well as low levels of cobalamin. The exocrine pancreas is responsible for secreting intrinsic factor. Intrinsic factor binds cobalamin to allow for gut absorption. Amylase and lipase concentrations do not provide reliable information regarding pancreatic function in cats.
Feline Calicivirus
common virus in cats that causes upper respiratory infection. Feline calicivirus is resistant to many disinfectants and can survive outside a cat’s body for several days
Feline calicivirus is spread between cats through direct contact with the eyes or nose of an infected cat or contact with contaminated objects that an infected cat has sneezed on or touched, such as food and water bowls.
Feline Central Retinal Degeneration (FCRD)
can develop from taurine deficiency. This is because photoreceptors contain large amounts of taurine and cats cannot synthesize it. The classic lesion is an elliptical area of tapetal hyperreflectivity starting int he area centralis dorsolateral to the optic disk that progresses to a horizontal band and eventually can involve the entire fundus.
Feline Herpes Virus
80-100% of cats become carriers post infection
coughing, sneezing, nasal discharge, conjunctivitis, and sometimes fever (up to 106) and loss of appetite
transmitted through direct contact only. It replicates in the nasal and nasopharyngeal tissues and the tonsils. Viremia (the presence of the virus in the blood) is rare. The virus is shed in saliva and eye and nasal secretions, and can also be spread by fomites. FVR has a two- to five-day incubation period. The virus is shed for one to three weeks postinfection. Latently infected cats (carriers) will shed FHV-1 intermittently for life, with the virus persisting within the trigeminal ganglion. Stress and use of corticosteroids precipitate shedding. Most disinfectants, antiseptics and detergents are effective against the virus
Feline herpes virus ocular manifestations
conjunctivitis, corneal sequestrum, eosinophilic keratitis, corneal ulcer
Feline Idiopathic Cystitis
most common cause of lower urinary tract signs in young healthy cats
Feline Immunodeficiency Virus
Lentivirus
Affects cytotoxic t-cells (CD8+), helper t-cells (CD4+), macrophages, b cell. After inoculation, replication occurs in lymphoid and salivary tissues. Eventually, the virus spreads to mononuclear cells, while viremia is suppressed the the host immune response (asymptomatic carrier phase) that can last several years. A slow decline in the number of CD4+ cells is seen, resulting in failure of the immune system. Cats are often about 10-15 years old by the time this occurs.
Feline Infectious Peritonitis Diagnosis
Fecal-oral transmission. Eventually, feline corona virus mutates to a virulent feline infectious peritonitis virus which is able to multiply in macrophages. Ideal, a strong cell-mediated immune response eliminates the virus, but in some cats, the infection can become latent and is reactivated with stress. If a cell-mediated immune response is not mounted, pyogranulomatous vasculitis will occur due to the deposition of antigen-antibody complexes in the venous endothelium.
Wet form: Complement-mediated inflammation results in pleural and peritoneal effusions
Dry form: Partial cell-mediated immune response results in slow viral replication with granuloma formation
Diagnosis: Highest positive predictive value: Immunofluorescence staining from coronavirus in macrophages in effusion fluid. Immunohistochemistry or RT-PCR used to demonstrate on biopsy specimens ( does not work on feces or serum). Histopathology is gold standard and can show characteristic lesions of disseminated pyogranulomatous and fibrinonectrotic reaction around small veins. Rivalta’s test.
Feline Leukemia Virus
retrovirus in the oncornaviridae subfamily and is transmitted both horizontally and vertically in cats. Virus propagates through the tissue, once bone marrow is infected, peripheral viremia occurs by infected neutrophils and platelets being released.
ELISA test for the p27 virus antigen in serum. IFA tests for p27 antigen in leukocytes and platelets.Test may turn negative after a few weeks in neutralized by the cat
Feline Panleukopenia Virus
Parvovirus
selectively damages rapid dividing tissues, namely the bone marrow and gastrointestinal tract.
Feline Parainfluenza virus
cause lesions in the distal airways and predispose to secondary bacterial invasion of the lungs
Feline Skin Fragility Syndrome
concurrent hyperadrenocorticism
Feline traumatic sarcoma
ocular sarcoma
Feline Viral Rhinotracheitis
herpesvirus and causes respiratory symptoms same as feline herpes virus
Glaucoma signs of chronicity
Buphthalmos, corneal fibrosis, lens luxations, mydriasis, tapetal hyperreflectivity and retinal vascular attenuation, and pale optic discs.
Heartworm tests
Antigen test will be positive if there are female worms present, but all male worms can show a false-negative test result
Antibody test is prone to false-positive results because a positive test can result from a cat that has been exposed but cleared the infection. A negative test cannot absolutely rule out infection as some animals with a low worm burden may not mount a sufficient antibody response to be measured.
Used together, they can be useful in most cases.
Larvae are more likely to migrate to ectopic locations such as the brain, skin, and ocular tissue.
Heinz bodies in the erythrocytes, blood glossy brown in color
Acetaminophen administration, the cat is showing signs of methemoglobinemia, which is caused by oxidative damage to the hemoglobin. Heinz bodies are usually present in animals with methemoglobinemia.

Hypertension
complications include hypertensive retinopathy (retinal detachment), hypertensive heart disease, neurologic complications, and progression of renal disease. Treat with Amlodipine - calcium channel blocker works by preventing calcium influx into vascular smooth muscle cells, thereby causing vasodilation.
Hypertonicity of urethral muscle
often post obstruction and urinary catheter making urinating painful and not easily controlled. Treat with phenoxybenzamine to reduce internal urethral sphincter tone.
Hypertrophic Cardiomyopathy treatment
Aim to improve diastolic filling by increasing heart rate. The primary problem with HCM is thickening of the wall of the left ventricle, impairing diastolic filling, there is usually no problem with contractility and systolic function. Slowing the heart rate provides for longer diastolic filling, allowing the left ventricle to fill more effectively. Decreasing the heart rate also decreases the severity of systolic anterior motion of the mitral valve. Medication most frequently used: beta-blocker (i.e. atenol or metoprolol) and a calcium channel blocker (diltiazem). For cases with severe left atrial enlargement or cats in heart failure also consider ACE inhibitors, diuretics, and preventing thromboembolic disease with aspirin or clopidogrel. Always keep in mind that you want to identify and treat possible underlying hypertension or hyperthyroidism that could be contributing to the disease.
IBR treatment
Budesonide or Prednisolone. Budesonide concentrates its effects in the GIT, thus has fewer systemic side effects as compared to prednisolone. Sulfasalazine and metronidazole can be used to help the condition by treating secondary bacterial overgrowth. Other treatments include easily digestible diet and one with a novel protein source, pro-motility agents or anti-nausea agents such as metoclopramide when needed, and vitamins such as cyanocobalamine (vit. B-12) or omega-3 fatty acids may also be of benefit in some cases.
Indolent ulcer
part of eosinophilic granuloma complex, history disappearing and recurring lip ulcer. These lesions can also extend into the oral cavity and can be found at the tongue base or hard palate. Typical treatment involves high doses of corticosteroids and identifying possible underlying allergic disease. Sometimes, antibiotics are indicated if severe infection is present. A hypoallergenic diet can be helpful if food allergy is the cause. Many times, the etiology is unknown but allergy is suspected.
Inflammatory Bowel Disease
Treat with corticosteroids (prednisolone or budesonide) to control inflammation, Sulfasalazine and metronidazole can be used to help the condition by treating secondary bacterial overgrowth. Easily digestible diet, novel proteins, pro-motility agents, anti-nausea agents, and Vit B-12 and omega-3 fatty acids may also be of benefit.

Mammary gland/ fibroadenomatous/fibroepithelial hyperplasia
most common in young, intact female cats due to increased progesterone exposure. Characterized by affecting one or more mammary glands, which become enlarges and are non-painful. Most affected cats are systemically unwell and do not show signs of illness or pain. Treatment if removal of the source of progesterone via ovariectomy or ovariohysterectomy. If no source of progesterone can be identified, or if the glands do no respond to spaying, a progesterone receptor blocker such as aglepristone can be administered as well.

Pemphigus foliaceus
Skin disease affecting the area of the head most commonly; specifically the pinnae, nasal planum, chin, or periocular regions are involved. The condition is pustular in nature, usually not observed on clinical presentation; instead, crusts are seen as evidence of ruptured pustules. The condition is thought to be immune-mediated in nature with potentially a genetic component. Drug-induced pemphigus foliaceous has been reported with the use of itraconazole.

Thiamine deficiency
Leads to seizures in cats fed diet deficient of Thiamine. Seen in cats few raw fish diets when thiaminase depletes the body of thiamin, which causes neurologic symptoms
Thyroid hormone active form
T3 - small percent is secreted by the thyroid glands, but the majority of it is converted to T3 from T4. Free T4 is unbound T4 which enters cells and can then be converted to T3 or reverse T3. Reverse T3 is formed during illness and does not have any known physiologic effect on cells.
