Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! Lack of growth and failure to gain weight in a kitten can be due to a number of medical causes- viral or bacterial infections and parasitic infections could be potential causes among others. I would recommend having the kitten seen by a veterinarian for an exam and assessment. You may wish to bring a fresh fecal sample to the vet appointment in case your vet wants to test the kitten's stool. I hope this helps and thanks for using Petco Pet Education Center, formerly Petcoach!
