Is Stubs a boy?

Hello,

Short while ago I took in this snow corn from a friend of a co-worker, they didn't want him anymore. He was missing a good chunk of his tail so I named him Stubs McGee. At least I think it's a 'he'. Here's a tail shot, what do you think? Does Stubs look like a boy to you?

thanks for the feedback and help!
