Bad Cat is generally not very odoriferous but has used the litter tray a few times recently to punish us for her incarceration in the local cattery. Though she did once plonk herself in my lap after, how can I put it, inadequate wiping. That outcome of that event involved both disgust and laundry in liberal quantities.
Anyway, I've just built her a large cat clambering tree for the bedroom. In fact I built it twice because I did it wrong the first time. Then it turned out I hadn't done it wrong and to be honest, I wasn't sure why I convinced myself I was wrong. Oh well. I was wrong about being wrong. Anyway, the aim of this structure is to enable her to get to the top shelf the wardrobe where she has taken to sleeping of an evening. Neither of us have any idea how she learned to open the sliding doors and clamber all the way to the very top to find a suitable nesting place. Anyway, it's a racket and it would be better for all concerned if she climbed something else to get there. And then there's the reverse, when she emerges. Imagine someone dropping a 5 kg bag of potatoes from ceiling height each morning. She actually sprained her front leg the other week (vet bill! vet bill!). The tree will, in theory, offer a more elegant route to floor level.
Of course, we know she'll ignore it and carry on as before. Cat owners can be identified by their foolish optimism when it comes to their pets.
