We put the flea collar on a week ago (not the drops) and it has left a collar mark like the picture on your main page….I read the message board and most stories were for the drops but we only used the collar but with same results….the cat is calm as usual but neck looks bad…..of course we have removed it and not sure what needs to be done. Do we give him a bath? take to vet? what should we do?
