My aunt got a new dwarf hamster for my cousin for Christmas. I have been keeping watch until Christmas morning and then I will surprise my cousin. I have put the hamster in its new enclosure, which is really small. My aunt did not know so please do not be frustrated. The hamster has been very inactive and has been staying in place for most of the day. This is the second day of the hamster being here. Is it possible sick considering the lack of movement. He has been in his little tube just sitting there sleeping.
