Cat got to pizza

[mylittlenugget]

So I live in an upstairs flat with my own front door. I had the door open as I was putting washing on the line and downstairs cat got into the flat. I had some leftover pizza out and it's eaten 3/4 of a slice.
Will it get poorly? It's clearly very hungry and so is their other cat that tries to get in to my flat so kind of want to say something but under the disguise of "oh your cat got in and ate some pizza so may get ill" but I doubt they'd care. What would others do in this situation?

Except, Chesterdraws, these really are hungry cats it seems. They are also neglected cats. They need someone to help them as they owners obviously aren't looking after them.

Shit, if they're selling the kittens they aren't going to want to get mum done. And this is one more reason why you should never buy kittens. It encourages this sort of irresponsible, neglectful behaviour. Get your kittens/cats from rescues folks!

Lasagne never seemed to do Garfield any harm

I don't believe the kittens were bred, more of an accidental pregnancy but it still shows their morals I think.
They made out like the birth was a surprise when even I (with no experience of female cats for over ten years and I was a child then) could see that she was about to pop any second.
The more I think about this situation the more horrified I am
