Over the next few days various scuffling noises here and there. It is clearly able to move about overground in the kitchen as it’s found another stash of bulbs and seeds left over from previous years which I’d completely forgotten about. So - yet more clearing away and throwing out (at least they were past their use-by dates). S thinks the trap might be a bit unstable as it’s across three pipes, not all the same diameter, so thinks we should have a bit of wood underneath to help. This, of course, involves more lying on the floor, fiddling about and more unintentional firings of the trap – which is very painful.
The following morning we discovered it had attempted to get at the packet of tea bags which were on the lowest shelf. It had gnawed a couple of holes but then evidently pulled the packet over on itself which must have frightened it into running away. Unless it just prefers coffee.
