Cute Cat

Daily attention to the litter box also serves as a monitor of the cat's health. Bentonite or clumping litter is a variation which absorbs urine into clumps which can be sifted out along with feces, and thus stays cleaner longer with regular sifting, but has sometimes been reported to cause health problems in some cats. Those with toxoplasmosis-infected cats living in habitat areas of sea otters may wish to dispose of droppings in the trash, rather than flushing them down the toilet. Some cats can be trained to use the human toilet, eliminating the litter box and its attendant expense, unpleasant odor, and the need to use landfill space for disposal. Training may involve four to six weeks of incremental moves, such as moving and elevating the litter box until it is near the toilet, as well as employing an adapter such as a bowl or small box to suspend the litter above the toilet bowl. When training is complete, the cat uses the toilet by squatting on the toilet seat over the bowl.
Feral cats
Feral cats are wild cats that are unfamiliar with humans and roam freely in urban or rural areas. The numbers of feral cats are not known, but estimates of the US feral population range from 25 to 60 million. Feral cats may live alone, but most are found in large groups called feral colonies, which occupy a specific territory and are usually associated with a source of food. Famous feral cat colonies are found in Rome around the Colosseum and Forum Romanum, with cats at some of these sites being fed and vetted by volunteers.
