That's going to be an awesome cave hide. I made on for Odahviing, and she loves it. It goes right into the corner, toward the glass, and I love it too because I can see in on her. The glass slides open so I can get her out of her hide if I need to. It's great to give them a spot to go to that naturally gives them a place to tuck in like they'd do in the wild. It feeds in to their natural instinct and just makes them feel that much more at home. Odahviing loves when I give her a nice, fluffy fleece. I make sure there's lots of extra material, and she scratches at it to make a nest. I've hypothesized that she's treating it like sand. I think that's why they like the blankies so much, and the pillows. I imagine it's a lot like scratching in a place to burrow to sleep and snuggle in. The way it conforms is a lot like dug up sand/dirt.
Blaze is getting so big and handsome. I love the picture where his back feet are flipped over because he's so relaxed. I always want to tickle the bottoms of their feet because they look so cute that way. Sometimes Odahviing will be hanging onto my shirt, and she'll start to doze off. Her back claws will loosen and let go, so I'll support her with my hand. Her back feet always invert lack that when her legs dangle. I love it because it makes me feel like she must be so secure and happy to be that at ease and relaxed.
