This program looked promising (come on, knowing what you cat is up to when you're not looking!?) but I found it pretty slow, a bit boring and generally poor in scientific-ish facts.
I would have liked to see less of the crazy cat people (okay, I'm one of them BUT I don't appear on a tv program about it!) and more of the actual footage of the roaming kitties...
You can watch it on BBC iPlayer until July
I caught a bit of Time Traveller's Guide to Elizabethan England too, and even if the form was pretty hilarious at times (but maybe it's just me being non-British?), I learnt a lot!
