So I got two kittens and while dealing with settling them in I didn't realize that the mouse I have fed my four month old BP was still there. I didn't realize this until I went to feed him his next meal which was four days later.

He gobbled the fresh one up but obviously the old one was rank-smelling.

What should I look for? When I took him out today it looked like had incomplete shed on his nose. But no other evidence he's shedding.
