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

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.

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

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

Cryptosporidium wrairi (intestinal protozoan characterized by weight loss, diarrhea, and death)
Fleas, mites, and lice (trixacarus caviae- zoonotic)
