Cannibalism In Rats

Literature Review
Conklin (1997) noted that in every individual the readiness to fight is greatest in the most familiar place: in the middle of its territory. As the distance from territory increases, readiness to fight decreases proportionately as surroundings become stranger and more intimidating.There is certainly evidence that aggression has a genetic basis, at least in some animals. Some strains of rats are inherently more aggressive than others. there are also differences in circulating testosterone levels between strains of rats, the more aggressive animals having higher testosterone levels and vice-versa.

Sarah Dray (n.d) investigated the diet of wild rats. Wild rats are opportunist omnivorous eaters which eat whatever they can find. In most cases, this includes grains, fruits and vegetables, seeds and nuts and any other edibles they might find.  However, they will hunt in sometimes, catching bugs and other small animals.
CPR (n.d) stated that rats.they reach social maturity at around 5-6 months of age. At this age, male rats in particular start to behave more aggressively toward each other. They shift from harmless play fighting into more serious adult fighting. They establish their hierarchy.
