Pet's info: Cat | Domestic Mediumhair | Male | neutered | 6 years and 6 months old | 12 lbs
I noticed my cat, 6tr okd male, had a lump almost the size of a walnut last Tuesday. Felt like a cyst, under the skin on chest, seemingly not attached to body. Softer, and round. Yesterday it felt oblong and almost pointy and firmer. Today it’s smaller, still firm but shrinking. Should we keep his vet appt we have scheduled for Tuesday. It seems like it is shrinking and would hate to bring him in unnecessarily.
