As nocturnal predators, cats use their acute hearing and ability to see in near darkness to locate prey. Not only can catshear sounds too faint for human ears, they can also hear sounds higher in frequency than humans can perceive. This is because the usual prey of cats (particularly rodents such as mice) make highfrequency noises, so the hearing of the cat has evolved to pinpoint these faint high-pitched sounds. Cats rely more on smell than taste, and have a much better sense of smell than humans.

Despite beingsolitary hunters, cats are a social species and use a variety of vocalizations, pheromones and types of body language for communication. These include meowing, purring, trilling, hissing, growling, andgrunting.[8]

Cats have a rapid breeding rate. Under controlled breeding, they can be bred and shown as registered pedigree pets, a hobby known as cat fancy. Failure to control the breeding of petcats by spaying and neutering and the abandonment of former household pets has resulted in large numbers of feral cats worldwide, with a population of up to 60 million of these animals in the UnitedStates alone.[9]
