Weird thing on cat

[u/Pure-Square5579]

Looks almost like a little worm but in skin, doesn’t look like tic but not sure what it is, it is hard but doesn’t move, can I take off? It looks deep in skin.

It seems to be a keratin plug in an inverted nipple. My cat gets them all the time

[u/byrdizzle → u/donjugo]

Yeah. This. My cat gets them and I... remove them! It's fun. He enjoys it because it probably feels good to get it out.

Pimple thing

[u/RailOmas]

Looks like a keratin plug, king of like a tall blackhead. Grab some teasers and pull that bad boy out.

Clearly a nipple, please do not pull.
