looking for advice on food

[Elementalzala]

Just wondering if there is anything these cats shouldnt eat, just that Bramble seems to eat everything (just like a dog), her favourite seems to be dog food which given that he steals hers if I walk out the room seems fair but she will quite often eat his food even when there is a full bowl of hers there, she also likes vegetables I discovered this the other day after leaving the dinner plates on the table while I put the kids to bed I came downstairs to find her munching her way through a piece of brocolli they had left so just wondering if there is anything she shouldnt eat that could be harmful etc
thanks
