Answer
Hi Dave,
At this age a lot of changes can start happening to our cats. Remember that an 11 yr old cat is about the age of a 82 yr old person. Any cat that needs to see a vet right away.

There are many causes of weight loss and kidney failure is just one of them. Cancer, leukemia and even just age alone will cause weight loss.

Have your dad get her in to see the vet soon. She needs care right away. There is nothing more I can tell you online, she really needs to be seen by a vet in person.
