There are many animal reservoirs of T. cruzi, all of which are mammalian. The most common domestic animal reservoirs are dogs, cats, rats, guinea pigs, mice, and pigs. The most common wild animal reservoirs are opossums, bats, rabbits, rodents, anteater, armadillo, sloth, and non-human primates. Dogs are the reservoir that most commonly spread infection to humans.
