Opossums (also called possums) are an animal species native to Oceania, but were introduced to North America. They were briefly mentioned in Ravenpaw's Path manga 1: Shattered Peace. It is believed that they come around the farm to eat Twoleg trash, fresh-kill items, plant matter, kittypet food and water, and maybe even small cats, the sickly feral cats, elders and kits.
