So I put Owen's cat momma on this (I had to order it from Amazon. Mamma gobbled it up (good!) but I notice she now has diarrhea, which is new for her and which it seems is the only possible adverse side effect from cosequin. I'm taking her off it for a few days to determine if this is actually the cause of her problem. Hard to say with her, since anything, and I mean anything from someone ringing my doorbell to a truck rumbling on the street stresses her and makes her hide for hours.

Anyway, just wanted to say that this supplment is great for any cats who can't be given anything directly.
