My bunny is 10 years old and can’t groom himself like he used to. His underside and legs need the most attention so what are some good clippers that can help matted fur and are gentle enough to use on delicate areas?
You could always find out what rabbit vets use. Probably more expensive, but likely the best kind.
Other than that, maybe look into what angora rabbit breeders use. They're the only other rabbit people besides vets, that might use clippers on a regular basis.
