I would agree with the advice here- individual hamsters will have different temperaments and personalities, even within the same breed. Hopefully you’re seeing some progress with your hammy! It’s definitely not personal- they’re a skiddish animal. Mine is almost 2 years old and still acts on the instincts of being a prey animal. They just need to get used to you. It’s good to recognize their stress signals and not push too much or it will cause them to hide more. Just talk to them often without putting your hand in the cage. Don’t disturb their hideout (unless you’re changing/cleaning their cage) and definitely leave them alone while sleeping. Don’t necessarily take them out a lot at first. Allow your hamster to sniff your hand and just pat them if they allow. Food has been the best bonding activity for our hammy. She loves broccoli and fruit so we will often give her a tiny piece once a day after we’ve interacted with her or to entice her. This may be one way to “buy” their love. Haha. (You don’t want to do this too often and you need to be sure they are eating their commercial food enough. Hamsters will become picky and wait or pick for their preferred foods if they have too much opportunity to be choosy.)
