My 6 month old kitten has had a lump between his ribs for an unknown amount of time (ever since I got back from a trip 3 weeks ago at least. I noticed it upon arrival but the person I live with hadn’t noticed). It was very large at first, at least an inch in diameter, but it has now shrunk to a centimetre maximum. It is between his ribs. I am unsure as to whether I should be concerned as it has shrunk so much.
