I think I'm clear; mine only eat the prescription type.
BUT...my dogs sneak in and eat the cats' food and one of them did develop bladder stones, which they think came from the high protein in the cat food, so people really should NOT feed cat food to dogs OR dog food to cats!
Take my word for it; it cost me $2000 to find out!
Ouch! expensive mistake. I bought one can of the science diet savory cuts by accident. My cats don't like it much. It didn't match the numbers, but it still makes me worry,
