I'll have a close look at the package when I get home. There were two kinds this place sold, and the girl from the store told me one was more geared to cats than the other. I'll have to try and get the name of that other one to see if I can find some info on the internet about it.
Thanks for the input guys!
One more question. Yesterday I took two medallions and put them in a plastic container in the fridge to have them thaw out. This morning when I broke it in pieces and mixed some of their canned with it, I noticed it was quite cold, and my guys hate cold food. Is there anything I can do to warm it up other than putting in the microwave which I'm thinking is a no-no.
There are only two rules at my house: House rule #1. Cats rule. House rule #2. See rule #1.
