I came home from work and discovered that my youngest kitten(5 months) has an opened wound on his back. I'm not sure how. Maybe fighting with my other cat? Any who, it's about the size of a quarter. It's not bleeding tho. It's officially thanksgiving day so my question is... Is this serious enough to call in the vet today? Plz excuse my ignorance on the subject. If it wasn't thanksgiving I would definitely have him in there today just in case. Any info would be greatly appreciated. Thank you.
