Ancol Small Animal Bristle Brush

My rabbit actually sits still for this, which never happens with anything else. The bristles pull out way more loose fur than I expected and her coat looks noticeably shinier after a few sessions. It's small enough to hold comfortably too.

The bristles are soft enough that my rabbit actually sits still for brushing, which never happened with our old comb. It pulls out a surprising amount of loose fur without scratching her skin.
