I use Cosequin as a joint supplement for my cat and it has helped Desi quite a bit. It comes in capsules and I just open the capsule and mix it in the food. Neither one of my cats mind it at all (is chicken/tuna flavor) and Desi is quite the fussy girl.
I usually order it from that link and order three bottles at a time. They ship it from California for free and it is usually about a week or so until it arrives.
