I have a 20 (yes 20)year old domestic tabby. She still eats and drinks and eliminates seemingly without problems. She is still active and jumps up on the bed or sofa to sleep. Slightly arthritic in the hips. She is however getting thinner and thinner. I can feel all of her bones and joints under her fur. I am inclined to simply attribute this to old age but I was wondering if I should try some sort of appetite stimulant. Any thoughts please?
