By weird I mean outside of regular cat diet, things like cornflakes, ketchup or banana bread (these are real examples from my and my friends' cats).
Glad I'm not the only one who has witnessed this insane behavior. I made the mistake of leaving a grocery bag with bread on the floor once and only once. My youngest cat went ape shit and I came back into the room to a bread massacre right through the plastic bag.
I have zero idea what drives this
