about the size of (albeit squiggy) gobstopper .. can't say how long it's been there, not infected but feel terrible just noticed it (due to small toddling dd always getting over excited cat rarely sits in one place these days!) he doesn't seem to be in any discomfort, still eating, walking fine etc.
He's getting on for 12 this year. Obviously need to take to vets, but, just wondering.. is it something awful, do I need to rush him there asap ? - DH (not overly keen on cat) 'kindly' suggested it was a tumor ??
