It is okay to eat. Cats can eat cream cakes and cake embryos, but they cannot eat cakes with jam, nuts, or chocolate. But whether to eat or not depends on the cat's mood. Some cats want to eat cake when they see their owner eating it, but they will only smell it after the owner gives it to them, and will not eat it. Cats are picky animals and usually only eat their own food. They will be greedy when humans eat them, but rarely eat after being given.
