It turns out, I can bring them back to the big playroom between adoptions events through the weekend. They did vocalize a bit coming home–Orchid was upset during the ride but happy to be back in the room. The cage at the shelter isn’t bad, but it isn’t a room. And I’m not sure these kittens can jump onto the shelf in it, despite it being a small jump. These kittens don’t jump much, which makes keeping things away from them a lot easier than with some litters.
I make felted rings from brushed cat hair and one of those is Orchid’s favorite toy. She does lose it under towels and furniture a lot, but it’s light enough to travel in unexpected directions when it gets caught on a claw and shaken off.
