Yes, maybe. But a tank full of fish takes even less maintenance than a cat. Not to mention hamsters, snakes, axolotls and even tortoises (by the way, my friendly pet-shop owner told me today, as he sold me frozen mice for the snake, that he'd heard of a lady who'd paid £600 in vet bills to treat a tortoise with a collapsed lung) . And for a totally maintenance-free (and cost-free) pet, there's always pet rocks.

This research result set me thinking. What sort of controls did they have? Was the result boosted by the inclusion of those of the lower orders who keep fierce dogs as trophies, mastiffs with names such as 'Asbo' or 'Semtex'? How was the result correlated to residence, given (I suspect) that a preference for cats might be dictated by whether the owner lives in a flat rather than a house, or the availability of outside space? And what about people who keep both cats and dogs? I think I shall have to go look at the original research (which indeed promises answers to such questions) and report back. But I have to take the dog for a walk first.
