Aww
I apologise for being a nosy killjoy.. Is that syrian always in that cage? If so I recommend an extension
syrians need a minimum space of 75cm x 45cm and minimum wheel size of 8inches but I wouldn't go less than 10 inches, it's important their backs are straight when running otherwise it can cause spine problems.
The ferplast KIOS is a little smaller at 70x40cm I think, I have one that my dwarf lived in but she's in the Zoozone2 now and that will fit a 12 inch flying saucer but will take up room, it will connect to that cage though. A cheaper option would be a bin cage, just mesh the lid and/or side and use ferplast or savic tubes to attach them
I think a 32L box fits a 12 inch flying saucer and leaves room for digging substrate
deep substrate is always good to offer as it's very natural for them to do
My syrian is in an Alexander from Zooplus, it was an investment cage as the bar width is small enough for dwarves too. It fits his 12 inch karlie wheel in fine and is a great syrian size. Also the Alaska from Zooplus which is a great price, with that and a 12inch Trixie wheel it comes to about £45 I think
Ignore me if I'm barking up the wrong tree and hammy has another cage or something
