Said It Here

Why does my cat act so destructive only when I'm home alone?

Cats can sense subtle changes in human presence or hormones and react by acting out with high-energy chaos like knocking things off shelves and excessive meowing. This intense behavior stops immediately as soon as another household member returns, leaving owners baffled by the sudden shift.

whenever i’m home alone with him, he wreaks significantly more havoc. knocks *everything* off the shelves, meows a lot, gets in nooks and crannies he otherwise wouldn’t bother with, gets a running start before jumping onto the counter so he can slide across and knock everything off at once...source ↗

as soon as my boyfriend’s back, normal cat!source ↗
