Thank you both for the advice. I didn't realise that the Omlet wasn't suitable as it seemed bigger than most store bought hamster cages. It's perfectly escape proof from my experience so far and the flooring isn't wire- there is a plastic plate that goes over the top of the wiring inside the cage. He seems to have no issue with the vertical tube either, I was just told not to keep dwarf or robo hamsters in it because they can't climb.
I'll have a look at the other cages for future reference but won't be swapping out right now as I've only recently bought it. I'll just keep the single hamster for now and think about things in future with regards to breeding- I was going to have a third cage for keeping the pups with mum but I'll post-pone this and do some more research first and reconsider my cage choice. It was just ideal because of the furniture look and also how easy it is to clean as that's a flaw I've found with a lot of hamster cages being difficult or time consuming to clean.
Thanks again
