My nearly 18 yr old cat "Bo" has small cell lymphoma, the vet is giving him steroids to make him more comfy & help him eat because he has lost weight in the last few months. He takes meds daily for hyperthyroidism. He seems ok most of the time but is declining. Has anyone dealt with this? I am wondering how long I may have left with him? He seems to still have his will to live, but he requires a lot of TLC which I gladly give. It also stinks that my other male cat has become aggressive toward him at times, but the vet said if I intervene too much it may make it worse for my poor Bo. Any advice?
