I'm using these Pet Natural joint support chews for my older arthritic cat. 2 chews daily. Because they're a little tough for her to chew - she only has a few teeth left - I break them apart and she seems to love them. They contain glucosamine & chondroitin just like people use to support joint structure. And they seem to be improving her mobility. I've only used for a month but plan on continuing them. Make sure you clear this with your vet especially a cat with any other health issues.

Pros: easy to eat chews, tasty,

Cons: consult vet before beginning

These would be great if your cat needed such a thing.

Pros: Healthy joints

Cons: expensive
