The selection of prey target is also influenced by hunger. Although hunger does not appear to affect the rate of hunting behaviour, larger, potentially more dangerous, prey will be targeted when cats are hungry <ref name ="Biben">Biben, M. (1979) Predation and predatory play behaviour of domestic cats. ''Animal Behaviour''. 27, 81-94.</ref>. In the same study, hunger was shown to increase the speed of killing behaviour, with satiated cats toying with prey for longer.

Apart from small mammals, birds and rodents, cats will also hunt and consume insects. Evidence for the specific nutritional contribution of insects to the diet of the cat is limited. However, insects (particularly spiders) are rich in taurine <ref name ="Weisenborn">Weisenborn, W.D. (2012) Sulfur contents of spiders and insects in desert riparian habitat.
