In the United States, the prevalence of obese or overweight adult dogs is 23–53%, of which about 5% are obese; [22] [23] the incidence in adult cats is 55%, [23] of which about 8% are obese. [22] In Australia, obesity is the most common nutritional disease of pets; [24] the prevalence of obesity in dogs in Australia is approximately 40%. [14]
Rabbits don’t meow like cats or bark like dogs, but believe it or not, when a rabbit is scared or angry, they’ll thump, which sounds a bit like a heavy textbook has just fallen off your bookshelf.
Rabbits play an important part in the terrestrial food chain, eating a wide range of forbs, grasses, and herbs, and being part of the staple diet of many carnivorous species. Domestic rabbits can be litter box trained, and—assuming they are given sufficient room to run and a good diet—can live long lives as house pets.
Heterothermy or heterothermia (from Greek ἕτερος heteros "other" and θέρμη thermē "heat") is a physiological term for animals that vary between self-regulating their body temperature, and allowing the surrounding environment to affect it.
The Himalayan rabbit and the Siamese cat are examples of artificial selection on heterotopy, developed by breeders incidentally long before the concept was understood. The current theory is that people selected for stereotypical phenotypic patterns (dark extremities) that happened to be repeatedly produced given a typical temperature.
Male rabbits are called bucks; females are called does.An older term for an adult rabbit is coney, while rabbit once referred only to the young animals. [1] Another term for a young rabbit is bunny, though this term is often applied informally (especially by children and rabbit enthusiasts) to rabbits generally, especially domestic ones.
Both rabbits and hares are almost exclusively herbivorous (although some Lepus species are known to eat carrion), [5] [6] feeding primarily on grasses and herbs, although they also eat leaves, fruit, and seeds of various kinds. Easily digestible food is processed in the gastrointestinal tract and expelled as regular feces.
Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate.Torpor enables animals to survive periods of reduced food availability. [1]
