When felines get obsessed with something, they won't stop until they've a) got it figured out, or b) done enough of it.

Some cats seem to be easily taken with rolling toilet paper. It seems to mesmerize them and they love unrolling them. It's annoying for the humans, unless you're Willie's owner Michael Thompson.

Thompson watches Willie play with a roll of paper, but after Willie is done unrolling the paper, he rerolls them back into a full bunch. Thompson is heard saying "You’re gonna pull it back up? I like that, I appreciate that. That’s very helpful. Thank you.”
