He hasn't been eating lately, and he is getting REALLY thin.

I am worried about him, he wont eat anything...wet food, treats nothing! All he wants to do is be around Callie...I am wondering if she is in heat? But I haven't seen anything to really suggest that...other than that area is a little swollen. But my baby won't eat! Any suggestions? I have tried separating them, and now they are both in their own kennels but next to each other, and they go out and eat at different times right now.
help!
