i used to have a hamster who would always get out of his cage, climb up the steps, and then he would be in my room, trying to climb things or hide in piles of clothes. it was bizarre and it probably happened like five times. probably more. he eventually passed after like 8 months of having him. for some reason, he tried eating his own bedding (like the hay for his cage) and suffocated. he had food in his bowl and plenty of water so i don't understand why he would eat it. i wasn't too sad because i was so young, but looking back he was such a weird little guy.
