Dr. Susan :

Hi, I can help you with your question today.

Dr. Susan :

No, this doesn't sound like cancer.

Dr. Susan :

This sounds consistent with two different conditions that are common in older cats: hyperthyroidism and diabetes mellitus.

Dr. Susan :

If I had to guess, I think she has hyperthyroidism. This is actually quite treatable once we have a diagnosis.

Dr. Susan :

Have you noticed any change in her about of thirst or urination? Does she have any issues with vomiting?

Customer:

I think she does seem to drink a bit more she is sometimes sick but not every day

Dr. Susan :

OK. This sounds very much like thyroid disease.

Dr. Susan :

It can be very well managed with daily medication called methimazole.

Dr. Susan :

I highly recommend having her evaluated by your local vet. I would start with a physical exam and senior screening bloodwork.

Dr. Susan :

This may be enough to diagnose hyperthyroidism (occasionally we need additional thyroid testing).

Dr. Susan :

Once we start medication at the appropriate dose, I expect to see dramatic improvement.

Customer:

many thanks, ***** ***** a appointment tomorrow.

Dr. Susan :

You're very welcome! Please let me know if you have further questions. I am happy to continue until I provide the service that you seek.
