My cat hasn't eaten the past two days but she still is drinking water and using the litter box. Should I be concerned? What should I look out for? Pet's info: Cat | American Shorthair | Female | 15 years and 1 month old | 8 lbs

Thanks for using Petco Pet Education Center, formerly Petcoach! This is in fact a concerning sign in cats as inappetence can be observed with conditions such as pancreatitis, kidney disease (most likely chronic in nature), dietary indiscretion and diabetes, just to mention a few possibilities. Cats can develop serious illness when they stop eating. This is known as hepatic lipidosis which is directly related to anorexia. I recommend that if Nutmeg is not eating by tomorrow morning, to have her evaluated by your veterinarian for further assessment and treatment. General labwork and thoracic/abdominal imaging may be recommended for work-up. Treatment would be based on findings. Good luck! Hoping for a speedy recovery!

Thanks for using Petco Pet Education Center, formerly Petcoach! Loss of appetite can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. Keep in mind that sometimes it is challenging and expensive to reach a diagnosis which does not mean that it is not possible to do so. Further diagnostics such as abdominal ultrasound and biopsies may be needed. I recommend that you have Sebastian reevaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a great day! Hoping for a speedy recovery!
