Tuesday: I think Rose is right on the money with that one - I had an older ferret who was on a really special diet and dry cat food was his main food (easy to eat/digest), but three different Vets (he was sickly and spent alot of time at the docs office) told me never to give him dog food, even the all-natural stuff cause his system couldn't break it down. I used to put some dry cat food mixed in the dog's food and that kept the dog out of the ferrets food dish. Even tho the ferret's passed on, I still give the dog some cat food mixed in, I think she's more of a chicken/fish dog then redmeat
