I found the owner today. It wasn’t Handsome at all.
It was Bart. His right bottom canine.
I noticed this this morning when I gave him an amoxicillan, which seems to help his funky eye. His breath doesn’t smell weird (any weirder than cat breath normally smells) and it didn’t seem to bother him. The tooth itself obviously came from farther down that you can see in this picture, so it’s most likely healing over.
*sigh*
Lovely. Just lovely.
