Im a first time Robo hamster owner and I am freaking out

[lauren_conly]

I just got my first pet Robo hamster 2 days ago. since I have put him in his cage he hasn't stopped trying to chew, climb up or squeeze through the bars. when I bought the cage the pet store staff member didn't warn me about it being too small or anything. I have got two wooden chews in his cage, which he completely ignores. there is also a wheel that he ignores as well. the cage itself is quite big for a robo hamster and has two different levels including the base and there is a long tube as well which he likes to it in a lot and sleeps there even though there is a house with bedding in it. as this is my first time being a pet owner I would be grateful on any advice or tips of what to do or anything I can buy for him as I am concerned he may escape even though the bar spacing is small.
