I was stroking my cat last night, and he was letting me touch his paws, which doesn't happen often, and I felt these odd little nubs half-way up his legs.
I found a cat physiology page
(albeit one in French), and if you scroll 1/3 of the way down to the illustration of the paw, I'm definitely not talking about the cat's "thumb" (called tubercule de pouce in the illustration). It could be the tubercule carpien, higher and on the right hand side, but my cat doesn't have a formed pad, just something that feels like a growth on each side.
Here's the really wonky thing: he has three honest-to-goodness whiskers growing out of each of the little growths. They are definitely not guard hairs- they are the same thick, glossy texture to his whiskers, and are definitely whiskers. They are about 1.5" long.
I've never seen this on a cat. Can anyone tell me what is going on here?
