My rabbit is about a year and a half old and is neutered. He lives with his brother. For a while now he has been losing fur and he is rather thin. When I bought the rabbits the woman said they were both neutered but I have a feeling only the skinny one is.
Fur and fleas:
He is missing fur on the sides of his legs, neck and his fur is thinning on his back and face. They live outside and I occasionally bring them inside for a few hours. I haven't done any flee treatments on them before but I have only had them for less than a year.
I feed them rabbit mix which has a lot of seed, grains and hay in it. I let them out of the hutch occasionally so they can have grass, I also occasionally give them treats like apples.
I'm not sure what's wrong with him. I want to take him to the vet but my parents won't let me. Is there a way I could get him to gain weight and regrow his fur?
