My hamster Olive has recently started to show signs of boredom by scaling on the lids of her cage and constantly trying to find a way out. I have her in an ikea detolf and have pretty much kept her cage design the same for the two years I’ve had her, and up until now she was perfectly fine. I’m not sure if I will get an other hamster after she passes away hence I don’t really want to spend a lot of money on a new cage but of course I want her to be happy in the limited amount of time I have left with her. Also she has been waking up a lot earlier recently and I don’t know if that has something to do with it or it’s just signs of her aging.How can I help her be happier? Here are some photos of her enclosure. ( sorry her cage is a little messy right
