Dog food doesn't contain Taurine... Dogs can synthesize their own, cats cannot. Without it the kitty could end up blind, suffer from heart failure, or develop some other kind of health problem.
There's a few other nutrients that cat food contains that dog does not, but taurine is the main one.
As long as the bulk of the cat's diet is cat food, a little extra dog food will probably do nothing except make her fat! |
