Ah yes, the results of over indulging in too many bunny intestines.
There was a follow up programme"Little Cat Diaries" shown on BBC2 the following night. One owner seemed suprised that her cat was sneaking into another cat's house and stealing it's food. I wasn't, that's how I got my last two cats, they just turned up, and moved in. Nor was I surprised by the cat which moved out when the owners got a large dog. although the woman was hurt that it preferred the dog-free neighbour to her.
Similarly, I wasn't too surprised at the results of the experiments with cats, separating them from, and then reuniting them with their owners, as they have done with dogs and children. Dogs and children will run to the owner/ mother and make a fuss, cats will barely turn a whisker.
