What's the most promiscuous thing you've known someone do?

My cat would mate with a different cat each time. She was Siamese and we lived in a rural village and wanted to breed her with another Siamese cat to get Siamese kittens. I would watch her like a hawk when she was in heat but somehoe she was an escape artist. She had 2 litters by different cats. The last time she came up
Missing for 3 days. I figured someone snatched her because she didn’t come back home to heat. Turns out she messing around with a damn skunk. When she came to the back door and howled to be let inside I picked her up and said “My baby!” Then I threw her down. She smelled like a skunk. Which explained why we were smelling a skunk at night around the house. I called her a couple of choices names after that. There was a cat at my neighbors but no she already had a litter of his kittens and wanted something different
