cats

I think it's OK for orange ones (source: Garfield). 😂 Actually, isn't there a lot of cheese in lasagna? Thought dairy wasn't great for cats (OK for kittens), no?

thought it was pizza. doubt they got any

Unless the cat is lactose intolerant, they won't likely suffer any significant health effects. Anecdotally speaking, my cats have not cared much for tomato based foods. My ex used to feed them bits of our human food to satisfy their curiosity. They'd eat the meat and cheese out of it and leave the pasta bits alone.

Then one of them would leave diarrhea on my most expensive furniture. Every fuckin time.
