Sylvie and the kittens are in the Jiro Palace, which is a big corner area that is secure, so she and her babies can feel safe and be safe. Tex has to live outside that area, so he has the rest of the office, which is quite large. I don’t believe he’s a threat to the kittens – he seems totally uninterested in them – but male cats do sometimes harm babies, so we’re erring on the safe side.
When I’m in the room, however, I open the doors to the Jiro Palace and Sylvie can come out. That’s her chance to explore the rest of the room. This morning she went up on the cat tree, noticed that the top cupboard was slightly open, put her paws up, nudged the door open further, and hoisted herself up. Tex saw her go up, and decided that he could just do the same thing in one jump. He was mistaken – he hung briefly by one paw, but then dropped – safely on a bag of kitty litter.
Tex missed his jump. 
A beautifully festooned Sylvie 
Sylvie came down, after exploring the back of that cupboard, festooned in cobwebs. In the evening she explored up there again, and came down even more gloriously bedraped.
I swear the kittens have doubled in size since yesterday!
