What’s a claw thorn? It’s what I call a claw that’s pierced the skin.

A claw thorn is a claw growing into a cat’s paw pad. Much like a thorn, an untrimmed claw can pierce the paw. Ouch!!

Claw embedded in paw. Happens more often with old or fat cats. Rare with young and healthy cats.
I call this a Claw Thorn. Claw embedded in paw. Happens more often with old or fat cats. Rare with young and healthy cats. When I trim the claw, the part that’s grown into the pad will come out. There’ll be some blood, and a small hole in the paw. Good idea to get your vet to check it out or at least keep an eye on it in case infection sets in.
