I have a neutered brother and sister (different litters so he’s 9 months). He is REALLY furry!!! and not that bothered about being super clean but he has to lick himself loads. His sister has only a small amount of silky fur. She grooms him and then he tries to groom her. BUT he about licks her head off coz he forgets she isn’t a big furry pompom. They have lots of space and toys. Vet has checked them both n given us some cream for her. She’s suggested separating them (just until she loses the bald patch behind her head). but we gave them a couple of hours a day together yesterday and today and then they are next to each other but are separated a wire thing the rest of the time. Is there something that smells or tastes bad or something that I can put on her head that makes him stop licking her near the bald bit, it feels cruel to separate them at all.
