Hello, and welcome!

It sounds from your description, like your cat is exhibiting classic symptoms of hyperthyroidism, which is not uncommon in older cats. Here is more detailed information:

There are other conditions that may cause these symptoms, as well, but a visit to the vet, where a routine senior blood panel, including a thyroid test can be done, will provide more diagnostic tools for the vet.

Hyperthyroidism can be treated easily with oral medication, a transdermal gel, rubbed into the inside pointy part of the ear, or a prescription food by Science Diet called Y/D. If she is diagnosed with this condition, your vet will help you decide which treatment is best for her.

I hope all will be well with your furry girl, once she is diagnosed and treated!
