My rabbit suddenly start hiding from me, he's not coming out and pooping less than normal and is smaller sometimes. He's also having red spots on ear and his limbs looking pinkish. The vet prescribed antifungal cream, multivit and avil tablet. Also scratching his ears. What should I do? Is he having some gut problem? I can't find a rabbit savvy vet here. Also he's eating less and not drinking water as much.
