You probably would have to add mesh to the corners of the Alaska for a robo. I have Russian dwarfs in Alaska and they've been fine but they're a fair bit larger. My roborovski Bub is in a custom built cage I found on Gumtree (i'll attach a picture) and it's perfect for him. If you're looking for something around 30 pounds I've never found anything better than the Alaska for the price and oh boy I have looked. The other options I'd recommend are Bin Cages (though you'd have to do some DIY) as there are lots of tutorials on YouTube and B&Q sell some pretty huge clear plastic storage bins for about 15 quid last time I checked if you're from the UK that is. Or check places like Gumtree/Craigslist to find something second hand, you might get lucky and find something great that's custom built like I did
