I have a Cat that looks like possum What is it called?

A cat that looks like a possum is likely a Minskin cat. The Minskin is a relatively new breed of cat, developed in the late 1990s by breeding the Munchkin with the Sphynx. Minskins have a short, sparse coat that gives them the appearance of a possum. They are also known for their small size and friendly personality.
