I won't argue about the "love" being a vital part of the equation for comfort. As for the feather pillow...that might double as a fun feline toy when they kick the stuffings out of it! I can just see feathers flying everywhere, and an innocent-looking kitty blinking amidst the mess...LOL!
Tuxedokitties has very good tips re: acupuncture and Cosequin. Cats are very good at hiding discomfort, and when they feel achy, they may just stop moving--or chasing their tail. Acupuncture is an extremely effective pain reliever that has no side effects. Prices vary in different parts of the country (about $50/session isn't unusual) and it may take a couple of sessions for the kitty to start feeling better--but it does work!
Cosequin is one of the few veterinary-tested products that contain the combination of chondroitin/glucosamine that is very helpful for joint health. It can slow down the progression of arthritis, and help the existing cartilage work better, and so ease discomfort. They also have antiinflammatory properties.
Of the generic forms, look for glucosamine HCL--they usually come in 500-mg doses, and cats need about 10 mg/pound of body weight, twice a day. That means a fifteen-pound cat would get about 1/3rd of a 500-mg capsule once each day. As hard as some cats are to pill, it's probably worth the extra cost to go with Cosequin, which is a bit more expensive and only available from the vet--it's more readily accepted by pets and is dosed properly.
Be aware that the glucosamine/chondroitin products won't work with all pets, but has great benefits for a certain percentage of cats and dogs.
