We have recently welconee a lovely rescue cat into our home. DDog is still trying to make sense of this hideous injustice.
DDog is a grazer, so her food bowl is always left down.
DCat loves DDogs food and goes over to eat it all the time (Royal Canin breed specific food). I try to stop DCat but he is quite persistent. DDog isn't bothered about the the cat eating her dry food (they are much more precious if it's roast chicken!)
Is is damaging? Will he get ill?
If he will, I will obviously have to try and do something different.
