Food
Place meat where the cat will have to work to get to it. This can be done by positioning the meat at a high level that the cat will have to jump or climb up to. Scatter food around the cat's exhibit so the animal must search for it to encourage the cat to be active. Toys that can be rolled around and made to release small amounts of food a little at a time will also keep the cats mentally stimulated.
Habitat
In a zoo each cat species should be provided with a suitable exhibit that is similar to the cat's natural habitat. Cat species that enjoy being in water, such as fishing cats, tigers and servals, should have a pool in the enclosure and will also benefit from a sprinkler system, which can be turned on as a treat. Cats that enjoy climbing in the wild, such as caracals and leopards, should have secure climbing apparatus available. Large cats must be provided with tree stumps to allow them to sharpen claws. Animals should also be housed in appropriately-sized groups, because some species, such as the lion, live in large groups in the wild, whereas leopards prefer to live alone.
Toys to Encourage Hunting Behavior
Cats can be encouraged to practice natural hunting behaviors with the use of enrichment items. This can be as simple as stacking up a number of cardboard boxes for the cats to tear down and rip apart. Another item that can be provided for chewing and jumping on is a rubber tire, which can be hung up or placed on the ground in the enclosure. For cats that enjoy water, provide large plastic balls for them chase and pounce on in the water.
Scent and Texture
New scents and textures can excite cats. Dip a hay-filled sack in the urine of a prey animal, such as a zebra, antelope or camel, and hang it inside the exhibition. Other scents that can be introduced include spices and various perfumes, which can be applied to a surface or object within the enclosure. A block of ice can provide cats with an interesting new texture, as well as an object that can be picked up and moved around.
