Early Stage Kidney Failure
Our mixed breed dog was diagnosed with very low kidney function at the age of about 13. We were told by the vet to put him on a low protien diet, so we purchased low protien dog food from the vet. We still fed him some meats occasionally as we didn't want to take too much away from him.
He lived to the age of 18 and we finally had to make the decision to put him down because he had difficulty getting up and even moving. His kidneys, though, were not an issue and we attribute much of this to the low protien diet.
Your case may be different, but maybe a change of diet will add some years to your kitty's life.
