kitty does NOT have to have fleas on her. IF SHE WAS EVER BIT BY A
FLEA SHE COULD HAVE
FLEA BITE DERMATITIS .....or an allergy
to fleas.
but yes she could also have an allergy to an ingredient in the flea treatment....
telling him NO, will only stop the action when you are around,its NOT solving the problem is it, and if kitty starts to become STRESSED out in your presence that will only make the problem worse.....he can't help himself, this itch is making him very uncomfortable.
