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?
