Have Cat Questions? Ask a Cat Vet Online.
Hello and thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 25 years experience and would be happy work with you.
It is difficult to talk about the treatment options when we don't know what the diagnosis is yet. With the symptoms that you describe, the top rule outs would be a potential overactive thyroid gland, inflammatory bowel disease (IBD) or intestinal cancer, but other conditions could be involved as well. It is really essential to start with a thorough physical exam and at least some basic lab work as the various causes mentioned would have different treatments or management strategies. An over active thyroid (also called hyperthyroidism - HT) can be treated with medication. IBD or intestinal cancer can be harder to confirm, but once other diseases are ruled out, we are often left with a cat that is "suspected" to have IBD or GI cancer as the cause of their weight loss and other GI signs. In those cases, even without further work up, some of these cases can be managed with medications and/or diet change.
I would urge you to schedule him for an evaluation with your vet soon. If you let them know of your financial constraints, they can help you to prioritize steps and proceed with the most cost effective plan of diagnosis and treatment plan.
I hope this is helpful. Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please reply so I can clarify for you.
