i agree 100% with what the other person said, please stop asking for advice if you aren’t going to listen to it. he may be surviving for now but he is not living a normal life at all, it is very important for his health that you get him a bigger cage with more enrichment. otherwise, you were responsible for causing this animal to suffer. the way he’s acting sounds like he’s declining and soon enough he will die from stress as the other person said. if that becomes the case you are responsible for doing nothing to help him when you knew you could have done something, and he will have lived an incredibly stressful life for what? normally i wouldn’t be so harsh but considering your other posts on this sub, and the content of this post, it is extremely important for this hamster’s health and safety to get him into a better enclosure, otherwise you will no longer have a hamster— and it will be your fault. i hope you listen to the advice people have been trying to give for the sake of this hamster’s life, thank you.
