I don't particularly like cats. I would have preferred the concept filmed with iguanas.
A trip to IKEA is hell on earth.
BUT the images they got at the end set to music were very nice.
Basically the cats (white only cast - call actors equity!) acted like they were at home. Walking on kitchen benches. Ignoring humans. During the shoot the sto-pid humans had to cut a hole in the wall to free a cat that was probably perfectly happy where it was, and capable of getting it's own way out. Ah, fun stuff.
