As long as we have had YouTube, we have had cat videos.
Cats on skateboards, cats sitting in chairs and cats on top of cats.
But just when you thought you had witnessed felines in every possible situation, think again, because a video of a cat involved in a steamy clinch with a SNAIL has emerged.
And what's more, there is another cat witnessing the decidedly creepy moment who looks JEALOUS.
Rip up the rulebook and forget everything you thought you knew about cat videos because this slimey ménage à trois has raised the bar.
Helpfully posted to YouTube under the Ronseal caption 'snail and cats', the video has attracted almost 150,000 views at the time of writing, proving that no matter how strange cat videos get, the public will still lap them up.
It's not clear what sweet nothings the snail was whispering to its four-legged friend, but we've never seen a cat as content as the one on the left.
Don't forget to browse the uploader's YouTube channel for a further clips of cats in circumstances you didn't even imagine, including a tower of cat food balanced on a sleeping kitty's head.
