My cat has lymphoma. How fast will meds help appetite and energy?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 11 years and 9 months old | 11.5 lbs

Hi trixie has just been diagnosed with small cell lymphoma. Just yesterday she started her first doses of Leukeran (one every 2 wks) and prednisolone (one every 24 hours). I know these meds are supposed to make her feel better and help her appetite, but how quickly can I expect to see these things happen? Thank you

It depends somewhat on the severity of her symptoms prior to treatment. Cats that minimal clinical signs and/or less aggressive disease often feel better/gain weight quicker. The steroid could help the appetite quickly as it is an appetite stimulant as well. Response to leukeran can take time, typically several doses (2 to 6 in most cases with this dosing scheme). Not every cat will respond (although the majority do) and it is important to make sure failure to respond is really a non response and not a drug related side effect (some cats do not tolerate this drug well, although most do with every 2 week dosing). Your kitty's doctor should help walk you through the process as well. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
