DEAR PAW’S CORNER: I hope this advice helps other cat owners. My cat, Ferris, is 13 years old, and while he’s generally healthy, he does have arthritis and is not as energetic as he once was. I noticed a few months ago that he was not finishing his dry food in the evenings, so I took him to the vet to get him checked out. Everything was fine, but the vet said that he might have some discomfort crouching down to reach his food and water.
