I had a cat that would eat all sorts of fruit from apples to mandarin oranges to strawberries. The bad thing is that my cat also really loved grapes, and if anyone knows anything about grapes and cats, they don't mix. It ended up making him really sick and my poor kitty ended up dying of kidney failure after eating a day lily which was the straw that broke the camel's back in terms of his kidneys. The takeaway from this is, even though you think your cat may know what is and isn't good for him to eat, be the backup plan to that and know what plants, fruits, or anything else a cat shouldn't eat and keep it away. To be safe, just stick with cat food, whether from a homemade recipe or a good reputable brand from the store. That's what I learned.
