As I mentioned in another thread, Leo has been upgraded to a Savic Plaza. It's early days, but I'm not sure if he likes it or not. I scatter his food all over the cage, even on top of his cube hammock, and he finds all of it so I know he's using all the space, but he's just not very active. He comes out to gather his food and doesn't seem especially nervous when he does that, but that's about all he does. As I say, it's early days so I'll give it longer and see if he perks up again. Maybe he just needs time to get used to the change.
The main issue is that he's stopped using his wheel. He has a new Niteangel wheel instead of his previous Trixie wheel but I don't think he's used it at all since the move. The first few nights I didn't hear him running but thought it might be because the Niteangel wheel is much quieter than the Trixie wheel. Then I put the Niteangel pedometer on his wheel and that reveals that he definitely hasn't been running at all (zero laps recorded).
As some might remember, he did previously sulk when I replaced one of his hides with a different one, so maybe he just hates the Niteangel wheel because it's different, or maybe he finds it too heavy, or too open, or maybe he just doesn't want to run because he's cross about the cage change. I think if he doesn't run at all tonight I will give him the Trixie wheel and see if he runs in that again.
