Have Cat Questions? Ask a Cat Vet Online.
Hello, I am Dr Ola and I am sorry to hear that your kitten isn't feeling well. It sounds as though Boone has a temperature (most likely from a bacterial and/or viral infection) that is causing his lethargy and anorexia. Unfortunately, given his age and small size, I strongly recommend that you take him to an after-hours emergency vet hospital right away. Once there, your veterinarian will examine him and complete the necessary diagnostics will most likely include a FeLV/FIV combo test, complete blood count and fecal examination. He will need fluid supplementation (either subcutaneous or intravenous) both to decrease his temperature and re-hydrate him. Kittens that are very small and not eating/drinking will become dehydrated and hypoglycemic pretty quickly; however, given the necessary treatment and medications can also recover quite nicely. Given his symptoms, taking him in today is the next step.
