Small lump under my cat’s neck for months, recently more noticeable - should I worry?
Noticed this lump a few months ago, but it’s more noticeable recently. It’s near the surface, moves with the skin, no pain when touched, and has a tiny blue-black-white like dot in the center. Cat acts normal otherwise. I did not see and legs of a tick tho. British shorthair 6 years old.
Could this be something like a cyst or should I get it checked?
