Thanks for using Petco Pet Education Center, formerly Petcoach! There are a few medications for appetite stimulation but my preferred ones are mirtazapine and Entyce. However, the best thing to improve appetite is to find out what is causing the appetite to be low and treat it. I would encourage you to check in with your veterinarian for further assessment and treatment. Good luck and have a great day!

    Mirtazapine is an effective medication that can increase appetite in cats. Needs to be prescribed by your vet and must be given at correct dosages (your local vet will tell you that). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further
