I have two pups but now I really want a cat to test this theory.
If you put a square (or as it turns out any shape really) on your floor, your cat will go sit in it. I didn't believe it at first either, but judging from all these tweets of people trying it out, definitely looks like it works!
There's no official reason why cats do this, some theories say it's about protecting what they think is a certain territory, another talks about small spaces to be in so they can conserve body heat. No matter what this is hilarious and kinda takes cats up a new level of funny.
Now don't bother me, I'm in my box. -Cat
Okay, I know you just tried it. Did your cat do this too???
