Well, we have at least one answer to why the beastlies are so bothered — there is a feral tom cat passing through. Not a wild cat, because he made so bold as to come in and spray my study. A quite unmistakable pong. Toms tend to be very aggressive towards spayed female cats, which would explain why the entire feline population is acting so cautiously. Coming in and spraying is self-evidently an action of intimidation addressed to Mrs Grey and the kitten, so I suspect they have been given something to be frightened of. Fortunately, the odour-removing spray you can get at the vet really does work & the atmosphere in here is now reasonably salubrious. What we need is Tiger Balm, I’m sure, but applying it could be a bit of a problem.
