my cat has something like that but its inside of her back toe also it has like eaten the pad off that was on that same toe. im really worried because its not hurting her that I can tell but every time I turn around she's licking and biting that toe. so if anybody has any idea what it is please tell me.
Please take your cat to the vet for an exam. Unusual growths and lumps need vet attention.
My previous cat had a lump on his paw. The vet did a biopsy and it turned out to be trichoblastoma, a type of benign skin tumor. The vet was able to surgically remove the tumor with clean margins. This may or may not be what your cat has. Only the vet can determine what it is and the best way to treat it.
