Week Six: Small Mammals (Part 2) Flashcards
What is the difference between male and female chinchillas?
Females have no labial folds
Males testicles do not descent into the scrotum, prepuce extends to directly under the anus
Gestation period of chinchillas
How many offspring are usually born?
138 days
1-3 born
Husbandry requirements for chinchillas
Heat and humidity, chew-proof, hiding places, mutli level homes, dust baths
Nutritional requirements for chinchillas
Hay supplemented with pellets, water bowls can be a hazard
Slobbers in chinchillas
Refers to clinical signs seen when malocclusion is present
Choke in chinchillas
Cannot vomit, object too large to swallow
Hairballs in chinchillas
Dietary fiber can help prevent hairballs
Heat stroke in chinchillas
> 80 degrees, high humidity
Behavior of chinchillas
Nocturnal, curious, rarely bite, athletic (even when old)
Restraining a chinchillas
Never scruff
Hold back end with one hand and the chest and forelimbs with the other
Fur slip
What is fur slip?
fur slip is done to “escape” the situation your chinchilla is in. Much like a gecko will drop their tail if caught be a predator (or accidentally picked up by the owner by the tail), chinchillas will release tufts of hair to get away from whatever is trying to capture them.
Venipuncture in chinchillas
Anesthesia preferred, jugular vein is primary
but can use cephalic, saphenous, femoral, lateral abdominal, tail vein
Behavior of guinea pigs
Docile and rarely bite, social and can share housing with other guinea pigs, vocalize, neophobic
What kind of teeth do guinea pigs have? Explain.
Open-rooted incisors, premolars, and molars
teeth grow throughout the life of the animal
Reproduction in guinea pigs
Females have pubic symphysis
Bred within six months of age
Copulatory plug may be found in cage
No nest building- precocious young (fully developed, born with hair, and the eyes open)
Husbandry for guinea pigs
Can be messy (no dedicated potty area, tip bowls)
Cages d not need lids to protect from escape, room temp should be around 70 F
Nutrition for guinea pigs
Herbivores: pellets, grass hay, fresh vegetables, limited fruits, cannot synthesize vitamin C
Scurvy in guinea pigs
Musculoskeletal disease caused by vitamin C deficiency
Clinical sings: lethargy, anorexia, arthralgia, uncharacteristic biting, diarrhea, weight-loss
Treatment: Supplementation and supportive care
Respiratory disease in guinea pigs
Caused by Bordetella bronchiseptica or Streptococccus pneumonia
Can contract from any carrier
Lumps in guinea pigs
Cervical lymphadenitis, inflamed/abscessed lymph nodes caused by Streptobacillus or Streptococcus
Isolation is necessary until healed
Zoonosis concerns with guinea pigs
Salmonellosis, sarcoptic mange, ringworm, lymphocytic choriomeningitis (LCM)
Restraint methods for guinea pigs
Method one: One hand supports the thorax and the other supports hind limbs
Method two: Similar but the Guinea pig is held in a cradled fashion
Restraint for jugular venipuncture similar to cats
Parasite concerns in guinea pigs
Cryptosporidium wrairi (intestinal protozoan characterized by weight loss, diarrhea, and death) Fleas, mites, and lice (trixacarus caviae- zoonotic)
