I’m at a friend’s place and the cat keeps bringing in dead (or half-dead) animals into the house. It’s my understanding that cats think we are big, helpless kittens that don’t know how to hunt. Hence, they think they are doing us a favour.
It seems like a few mice actually escaped and found refuge in some walls in the house, so these “presents” are actually more than just annoying (and smelly if the dead animal ends up behind the couch).
Imagine how frustrating it’d be trying send an intimidating message with all the dead animals but the intended recipient just thinks you’re trying be helpful in a misguided way
