I have a very sweet female hamster who in the space of one night managed to chew her way out of her cage and was found running around our spare bedroom. 
The hole is impressive. I don’t know how she managed to chew through plastic. We have had other hamsters in a similar cage and not one has ever chewed their way out.
Hamster is currently living in our utility room which luckily is escape proof but not ideal. I have spent ages researching other cages but they are all tiny and most plastic.
Any ideas on alternative cages? The problem is now that she has been running free she has become quite feral, I just picked her up for a cuddle and she made the most awful screeching noise.
