My parents kept getting me hamsters when I was a kid, it's crazy how high maintenance they are if you actually want to keep them in good conditions :(
(not like they cared that I kept them well or were willing to provide me with the resources to do so tho)
don't remove all the poop, and don't clean off all the pee
rodents mark their territory with their smell, i've seen my rats sleep like cozy babies on a pissy blanket so many times. If you remove all their smell, that just makes them work harder to poo and pee on everything to get the smell of home back
It's a plastic carrier for transportation, not a literal metallic cage. I'm unsure how it's called in English. I put it high on a shelf, he likes it, it's his safe place. Of course, it always open, I detached the door, put a blanket inside. Sorry for the confusion.
