glucosamine treats

I have a senior cat, Spooky, who is experiencing arthritis and it hampers his mobility.  My other senior, Mouse, is just beginning to get a little stiff.  I have had difficulty finding very many glucosamine products for cats; chew treats seem to be the only thing.  They have been on some, twice a day, for over a month.  I feel like I am not seeing a great deal of difference.  Has anyone had any experience with these, good or bad?  I have a lot of animals and can't afford to be buying them if they aren't helping, as they are pretty expensive!

I had much better luck with Adequan injections than feed-thru supplementation, but many still swear by Cosequin and other formulas.  Treats generally don't contain enough of the good stuff to help.

It might take more then a month to work, supplements can take a long time. Some antidepressants for people take up to 3 months to start in! I would keep giving for 3 months to see if they work, good luck!
