Without photos I’ll paste in exactly the setup I have using links, I don’t think it’s possible it is too small lol. Plus when we bought him this is what the pet store recommended.
He is around 13 weeks old.

Habitrail Twist Hamster Cage, 48.5cm x 19cm x 24cm https://www.amazon.co.uk/dp/B0055Y5DT4/ref=cm_sw_r_cp_api_4EWdAbZR0ZE65
I have removed the wheel out the main suite so there’s more space so he only has the wheel in the twist.
It looks like human blood when dried?
