I know that JB (the kitten) is getting enough of her own food, but sometimes she will walk away from her own food to eat Daisy's. She also will only drink out of Daisys water bowl not her own. What's up with that? Is it ok for her to get a few peices of dog food?

yes its ok but its not good for them if they are consuming alot. My cats try to sneak out some dry dog food from my dogs also when they are eating.
