This has been used as evidence that the purpose of brain and nervous tissue is primarily to produce movement. Self-cannibalism behaviour has been documented in North American rat snakes: one captive snake attempted to consume itself twice, dying in the second attempt. Another wild rat snake was found having swallowed about two-thirds of its ...
In comparison to rat snake species at relatively colder regions, rat snake species at lower latitudes tend to be larger in size due to warmer climate conditions. As the global climate warms, the average body size of rat snakes at higher latitudes will become larger, which will allow the species to catch more prey and thus increase their overall ...
The snakes can also eat young chickens and chicks, hence the common name chicken snake. Rat snakes are most vulnerable to predators as juveniles. Predators of P. alleghaniensis include hawks (Buteo spp.), great horned owls (Bubo virginianus), foxes, raccoons, and domestic cats. Adult eastern rat snakes have few known predators other than humans.

Hence the snake eating its tail is an accepted image or metaphor in the autopoietic calculus for self-reference, [30] or self-indication, the logical processual notation for analysing and explaining self-producing autonomous systems and "the riddle of the living", developed by Francisco Varela. Reichel describes this as:
The latest encounter showed that a hungry adult snake can eat a sizable gator. Such clashes, though spawned by damaging incursion by an exotic species, can’t help but fascinate both the public ...
Infection with Toxoplasma gondii has been shown to alter the behavior of mice and rats in ways thought to increase the rodents’ chances of being preyed upon by cats. [ 31 ] [ 32 ] Infected rodents show a reduction in their innate aversion to cat odors; while uninfected mice and rats will generally avoid areas marked with cat urine or with cat ...
The beauty rat snake typically feeds on ground rodents such as mice and, due to the snake's climbing abilities, even bats that are roosting within the caves they share. In addition to small mammals, beauty rat snakes have also been known to eat birds and bird eggs occasionally. [citation needed]
