I had a couple over the years, poly-dactyl inbreeding cause some of them to have splayed paws, and for all appearance and to a large extent an opposable looking thumb, I’m not kidding they would hold something just like they had a human hand.
Climbing? Like they had a rocket under them.
We have two polydactyls, and one of them is nicknamed “Shotgun” because he doesn’t even have to aim to catch something—front paws are soooooo big.
