Our cat has a lump half way down her back and to the left of her spine. I noticed this last week after cuddling. It doesn’t bother her when I touch it. She’s been on steroids for 6 weeks previous to this observation for scratching her neck constantly, and her behaviour has been affectionate, lively, eating constantly, drinking, playing, so normal. After her visit regarding the lump last week, the vet suggested it could be an osteosarcoma and suggested biopsy, x Ray etc. She also observed a decrease in weight of 800g in 6 weeks (despite eating WAY more than normal). I decided to think about our options vs cost and brought her home. She hasn’t been the same since. Lethargic, barely eating - just a few nibbles of kibble, licks gravy off wet food, no more treats- and just generally not herself. We took her back in to get a steroid injection since she has stopped taking her tablet steroids and the vet thought her stomach was a bit distended and could have cystitis (something she’s always suffered from) but no treatment offered, just to keep an eye on her. But she’s just not her usual self at all. She’s not peeing more than normal but is drinking more often (steroid side effect?). I just have no idea why there is such a sudden change in her behaviour. Any suggestions? She’s a fussy eater at best of times so we keep to the same food with hair ball control. Felix gravy wet food as a treat. Is it coincidence she became this way after her first vet visit? We couldn’t go in to vets with her because of Covid so no idea what happened in there. She’s usually fine about going to the vets. But her whole behaviour changed since the first visit. I’m worried about her so any advice would be hugely appreciated! Vets is closed until 29th December and her condition doesn’t appear life threatening.
