I have. Random outdoor cat walked over to me, demanded pets, it noticed a bird, killed the bird, and came back to me looking for more attention. I was not impressed.

I have feed around 10 stray cats for the last 15 years. Only one of them was a hunter, and by that, I mean it's like watching captain Levi dealing with giants. I once saw her take down two pigeons at the same time.

I grew up in the country with outdoor cats. Birds, frogs, bats, mice... sometimes alive sometimes in jigsaw mode

Dang, we had barn cats as a kid, and then dad let one inside, and then more, but they would demand to go outside regularly so my parents let them, but the prettiest one, a calico, was always so proud of her catches, she'd leave them on the welcome mat like a present. Sometimes the whole bird, somtimes just like the feet left, she must have been hungry those days.
