Ok so my boy lily has taken on a nurturing attitude ever since I got my baby girl rose. He loves grooming her and makes her bleed behind her ears cuz it's kinda raw there from his nibbling. No open cuts but theres always red dried blood marks there. A vet has said to discourage the grooming but I usually dont see to stop him. Is there a human product I can put there to make it feel better or maybe just discourage the grooming from bad taste or something? Like I said no open skin there the vet said so its not a cut.
