Pairs or groups of any sex (depends on personality)
Sleep together in piles
Why is GI disease very common in ferrets?
Very curious - will attempt to eat almost anything
What conditions may cause a ferret to ingest a foreign body (pica)?
Hepatopathy
Inflammatory bowel disease
Why does foreign body ingestion in ferrets show rapid clinical signs?
Ferrets have a short GI transit time
What is a trichobezoar?
Ingested mass of hair
Are trichobezoars normal or pathological in ferrets?
Can be either
Due to self grooming or pruritic skin disease
What bacteria causes GI infections (and anaemia) in < 2 yrs or stress/sick ferrets? (or a recent diet change)
Helicobacter mustelae
Chronic Helicobacter infection in ferrets can use to development of what tumours?
Gastric adenocarcarcinoma
Gastric mucosa-associated lymphoid tissue lymphoma
How is Helicobacter mustelae in ferrets diagnosed?
Silver staining to visualise organism
Serological assay
PCR on gastric swabs PLUS gastric biopsise
How is Helicobacter mustelae treated in ferrets?
Ranitidine/omeprazole
Antibiotics - metronidazole, amoxicillin
What type of pathogen causes Epizootic Catarrhal Enteritis (green slime disease) in ferrets?
Coronavirus
What are the symptoms of epizootic catarrhal enteritis in ferrets?
Green, mucoid D+
V+
Weight loss
Is Epizootic catarrhal enteritis more severe in younger or older ferrets?
Older ferrets
How is epizootic catarrhal enteritis treated in ferrets?
Supportive care
Broad spectrum antibiotics
GI protectants
Quarantine
Ferret systemic coronavirus resembles what virus in cats?
FIP
Dry form
How is ferret systemic coronavirus diagnosed?
Bloods - hypergammaglobuniaemia
Does ferret systemic coronavirus tend to affect older or younger ferrets?
Young ferrets
Survival for 2 months
What bacteria causes proliferative colitis in ferrets?
Lawsonia intracellularis
What is salivary mucocele?
Abnormal collection of saliva leaked from damaged salivary glands/ducts
Which glands in ferrets produce their typical ‘musky’ smell? Do males or females have a stronger smell?
Sebaceous glands
Males
When do ferrets usually moult?
Spring/Summer
What type of ovulators are ferrets?
Induced ovulator
Why is it an issue if jills are unmated?
Oestrogen toxicity
Unmated = remain in oestrus, 50% develop aplastic anaemia
What are the clinical signs of oestrogen toxicity in ferrets?
Swollen vulva Pale mms (aplastic anaemia)
How can oestrogen toxicity be prevented in ferrets?
Use of a castrated male
Neutering of female
How can oestrogen toxicity be treated in ferrets?
Proligestone injection or hCG
Blood transfusion
Is adrenal gland disease the same as Cushing’s in ferrets?
No
At what age do ferrets usually present with adrenal gland disease?
3.4 yrs post neutering
Which area/zone of the adrenal gland is affected by adrenal gland disease in ferrets?
Zona reticularis
Elevated androgen hormones, hyperandrogegism
What can cause adrenal gland disease in ferrets?
Genetics
Indoor housing/photoperiod
Neutering!
What are the clinical signs of adrenal disease in ferrets?
Androgen stimulation Bilateral symmetrical alopecia Pruritis Behaviour change/aggression Vulval swelling Gynaceomastia (males develop breast tissue) Prostateomegaly causes dysuria
How can adrenal gland disease in ferrets be diagnosed?
History/clinical signs
Serum adrenal panel
Abdo ultrasound and palpation if enlarged
Treatment trial
How is adrenal gland disease in ferrets treated?
Surgery - find cause (e.g. ovarian remnant), L adrenalectomy
GnRH analogue - Deslorelin implant
Melatonin
When treating adrenal disease in ferrets, why is only the left adrenal gland removed?
Right adrenal gland is attached to caudal VC
Debulk instead of removal
Are GnRH analogues (e.g. deslorelin implants) better in early or later stages of ferret adrenal disease?
Early stage
Less effective if advanced/neoplastic
What tumour is associated with ferret adrenal gland disease?
Insulinoma
Measure glucose
How can adrenal gland disease in ferrets be prevented?
Keep ferrets outdoors
Alternatives to neutering - deslorelin, progesterone, vasectomised mating
How often does the deslorelin implant last in ferrets? When should it be placed?
1-2 years females, 4 years males
Place in Spring
Is the deslorelin implant licensed in ferrets?
Only males
Entire male ferrets can be difficult to handle due to very strong musky odour. What are the treatment options?
Castration
Deslorelin implant
Neuter and implant at same time if adrenal disease
What tumour is relatively common in ferrets
Insulinoma
Are insulinomas more common in males than females? What age?
Males
4-6 yrs
What are the clinical signs of insulinoma?
HL weakness/ataxia Stargazing Dull Seizures Collapse Salivation/pawing at mouth (nausea) May resolve following meal
What surgical treatment can be used for insulinomas in ferrets?
Partial pancreatectomy or nodulectomy
What medical treatment can be given for insulinomas in ferrets?
Prednisolone - for gluconeogensis
Diazoxide - to inhibit insulin release
Other than medical/surgical treatment, how can you manage an insulinoma in ferrets?
Emergency stabilisation with glucose
Diet high in fat and protein - no simple sugars
Is dilated cardiomyopathy related to taurine deficiency in ferrets?
No
What is the most common echocardiographic finding in ferrets?
