I have rescued two Japanese Bobtails from a somewhat neglectful situation. They both have uterine and bladder infections for which they are on Clavamox. They have been eaten up by fleas in the past and are thin. I am a German Shepherd Rescuer and I don't know that much about cats. Can someone recommend a good supplement that will help their skin/coat and overall health. I am currently feeding them Hills C/D because of the bladder infections. They just got spayed. One of them has some leakage, I'm hoping just due to the infections. I work for a vet but they aren't a lot of help sometimes. I am trying to find a rescue or a forever home for these sweet girl kitties.
