My 1 and half year old holland lop has some matted fur on her bottom. Not sure how this became a problem since I give her a small amount of pellets each day along with timothy hay. Some poop is stuck to her bottom too. I tried to brush out her matted fur, but it wouldn't come out, and I'm afraid of hurting her. I have a nearby vet and she has already gone to the vet once for a check up. I was wondering if anyone's bunny gets matts easily and tips of how to prevent it. Also, I'm wondering if vets would be willing to remove the matted fur and how much it usually costs?
