Cat Doesn't Know How Doors Work, Disaster Strikes (VIDEO)

Hello and welcome to the latest video instalment of our occasional feature: 'Silly Cat Of The Day'. And today's star is Sofia - beloved pet of YouTuber Yasmin Medeiros - who pays the price for forgetting how doors work.

Any points to note? Well, listen out for the little squeak when disaster all too inevitably strikes. And we adore the expression on the other cat's face as he/she turns to camera: "Mother! Do something!"

Oh, and don't panic, folks. We have it on good authority from Yasmin that Sofia was totally unharmed. Indeed, she climbed up the shelves to do exactly the same thing five minutes later. Cats, eh? What are they like?
