Many animals at the Zoo receive whole prey in their diets. Reptiles, birds and smaller mammal species are fed whole prey including mice, rabbits and fish. African lions, cheetahs, vultures and other carnivores are fed portions of whole carcasses.

The vast majority of the animals held captive inside their compounds are depressed. They live in perpetual captivity and lack access to all of the things that make life interesting and enjoyable. And, often, they die far earlier than they would if they lived in nature. As it turns out, zoos do far more harm than good.
Most big zoos have a fulltime staff of veterinarians and other health experts. They examine the animals and treat them in case they become ill. However, even in zoos, animals can get hurt.
Lions can't be tamedOne interesting study found that lions are entirely unsuitable to life in captivity (Clubb & Mason, 2003, 2007). In the wild, lions have one of the largest home ranges of all large carnivores, in which they travel in on a daily basis.
So what do zoos spend money on if not the animals? Staff salaries, animal maintenance and facilities costs are the obvious expenses, but there are others. For example, in 2021 the San Diego Zoo spent $15,084 on advertising, according to the zoo's financial statement.
In the United States most zoos are supported partially or wholly out of public funds by the town, city, or state in which they are located. The National Zoological Park, in Washington, D.C., was founded by Congress in 1889–90.
What we do know so far is that evidence suggests wild animals can be as happy in captivity as they are in nature, assuming they are treated well. Confinement alone doesn't mean an animal is automatically worse off.
MYTH 4: Animals in Zoos are happy. Animals in captivity across the globe have been documented displaying signs of anxiety and depression. In fact, psychological distress in zoo animals is so common that it has its own name: Zoochosis.
To meet our big cats' needs, we feed them three diet items: whole rabbits, which are a good substitute for the skin and organs of large prey; ground meat, representing the muscle tissue of a kill; and bones, which help our cats maintain strong jaw pressure and clean their teeth.
After an animal dies, a necropsy is done to determine a specific cause of death to list beyond simply euthanasia, and the results are added to the animal's permanent file. Once this testing is completed, the remains of the animal are cremated.
Captivity suppresses the natural instincts of wild animals. Animals suffer permanent frustration because they have no freedom of choice and cannot behave as they would do in their natural environment. This leads to a tendency toward genetic, physical and behavioural degeneration.
Most boids, pythons, vipers, colubrids, crotalids, and elapids are fed mouse pups, mice, chicks, hamsters, rats, guinea pigs, chickens, ducks, or rabbits. Frozen, thawed prey are usually used in zoos; thawing under refrigeration is recommended.
Only in very special circumstances do zoos obtain animals from the wild, which is illegal in many nations. Thus, zoos are not in the practice of actively capturing animals in the wild from their natural habitats.
Yes, there are many poorly run zoos/aquariums/sanctuaries, but there are also those who fight hard against extinction, reintroduce species on the brink of extinction, and work with governments and communities to protect species and house animals during rehabilitation and recovery.
