If you have a rabbit, guinea pig, or chinchilla, please read this.
Small mammals do not handle heat the way cats and dogs do. They cannot sweat or pant effectively. Rabbits should not be in environments above 75-80 degrees Fahrenheit. Chinchillas are even more sensitive (they can overheat above 75). Guinea pigs are vulnerable above 80.
The dangerous part is that small mammals will often stop eating and become lethargic before they show obvious signs of heat stress, and once they crash, they crash fast.
What helps:
1. Move enclosures to the coolest room in the house (basement, interior room).
2. Frozen water bottles laid against the cage on hot days.
3. A fan running nearby (not blowing directly on the animal).
4. Ceramic tiles in the enclosure for a cool surface.
5. Avoid car travel during peak heat.
If your small mammal is breathing fast, drooling, lethargic, or stretched out and not moving, this is an emergency. Call us at 608-294-9494, or for after-hours, UW Veterinary Care (608-263-7600).
