I've known Crosscheck for many years. He was dumped on a friend's property, and another friend took him in. As you can tell, by his name, Crosscheck is a big hockey fan. He always has RPI hockey season tickets, or wait ... it's his dad that has season tickets.
Anyway, Crosscheck lives with his two sisters, Slapshot and Zamboni, who were adopted from Whiskers. Crosscheck has diabetes, and needs insulin injected twice a day. He's a good sport about it!
