Hello livvrheaa and welcome to the forum. You sound so caring towards your hamster. I was wondering if you would feel more comfortable having your hamster in a snuggle sack? I saw a youtuber called Victoria Rachael uses one sometimes. This is a little sack of a soft material were the hamster can go inside. I will put a link of one for you.
