Option D is my guess, though maybe not in that order. I think the food ones would come first, probably the easy access food bowl followed by the Dreamies cupboard. NDN's last, definitely.
The question arises, why did you have an open tin of black gloss paint?
It's tomorrow I'm going Lana. DSis is coming as my common sense, as I can't be trusted with loads of cats around not to pick either a) the neediest or b) the cuddliest, whether suitable for Girlcat or not. Also, she will be the one to stop me if I try to settle for the best option there even if it isn't really right, and make me wait for the right one. Nephew No. 4 has been invited as we reckon his brain is part cat anyway - he was the first person other than me that Girlcat let touch her, and just about the only male that Boycat could cope with being in the room without fleeing in panic.
I think it is starting to get urgent. Girlcat was in a right sulk last night, instead of charging down the stairs the second I walked into the house, she stayed on her favorite upstairs bed of the bottom of the wardrobe - I ended up going upstairs to check on her after an hour as I was worried. Then when I went to bed, I could hear her wandering about the house squeaking - they used to do zoomies chasing each other up & down the stairs just after lights out.
