Keeping animals happy as well as healthy is a challenge. The best way is a combination of several things: physical interaction with others of its own kind or specially trained human companions, desirable features in the enclosure such as swimming pools and ledges for perching and sleeping, and toys to play with. (21) Sometimes food is hidden about or put on ropes where it can be jerked away to stimulate chase, hunting, and play behaviors. Many zoo animals are fond of visitors and develop routines to impress the people that come to see them. (22)Large, natural enclosures gives the animals more freedom of movement and encourage physical activity.

Question

2 (23) While most modern zoos do not teach animals to perform "tricks," they do train animals to respond to certain commands to make them safer to handle, move and for examination. This training emphasizes rewards for good behavior rather than punishment for bad behavior. (24) Using the reward system not only makes training easier and more humane, but it also avoids the ever-present danger that an angry cat may find a chance to lash out at its tormentor. That only needs to happen once briefly for tragedy to occur.

3 Although it is unpleasant to think about, death is a part of life. (25) A decision is made by the zoo staff that a certain cat is in too much pain to have a good life, when the life of that cat is humanely ended. The phrase put to sleep or put down is not accurate and does not confer the dignity that usually accompanies the act. Zookeepers almost always experience grief when one of their long-term friends dies. (26)Whenever possible, someone the cat loves is allowed to be there since the drug is administered. This special drug is designed to calm the cat and lull it to sleep before death occurs. After death has been certified by the veterinarian, a necropsy (animal autopsy) is performed to determine the exact cause of the animal's illness or injury. This information is used to help protect other animals. (27) Many zoos, and most sanctuaries and animal parks, have special plots where beloved animals are laid to rest. These are rarely open to the public. (28) If animals that are not buried are usually cremated (burned) for health reasons or used to provide skeletons and skins for educational use at the zoo or in museums and universities.
