Cats often are not constipated but are having diarrhea. With her age I would be concerned about a disease causing a decreased appetite. I would recommend taking her to a veterinarian for blood work and possible x-rays. At this age kidney disease, cancer and hyperthyroidism are very common. Also bad dental disease can cause a change in appetite. She most likely has an underlying disease that is causing her these secondary issues. I do not think changing her diet will be enough to make her feel better. A veterinarian visit is best. Hope she feels better soon

    Thanks for using Petco Pet Education Center, formerly Petcoach! Loss of appetite and weight can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. I recommend that you have Sensation evaluated 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. You can add a teaspoon of canned pumpkin to his meals which can help with constipation. Good luck and have a great day! Hoping for a speedy recovery!
