Hi there and thank you for using PetCoach to address your concern. I would recommend having an abdominal ultrasound performed to help further rule out other causes such as lymphoma or other cancer in the abdomen. With an older cat I worry about these types of changes that could be contributing to the weight loss due to malabsorption from intestinal disease. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
