I’ve only had Syrian hamsters, but all 6 of mine have made squeaking noises on occasion. Similar to what you described: smaller quicker noises instead of the loud noises of fear or pain

I would just pay attention to whether your hamster continues doing it and whether any other symptoms appear

meanwhile, it wouldn’t hurt to ask the vet about it when they open in case it might mean something else, but squeaking isn’t necessarily a bad sign

I wish the best of luck to you and your hamster
