Others may not want to take the hamster in either. Most of the time, very sick hamsters have little chance of survival. The vet bill is also often much higher than the price of the hamster. This can prove to be terribly irritating. This might not appeal to extremely tidy pple who like to see their house spick and span at all times.
Hamsters are crepuscular or nocturnal.
Basically, they're awake and active in the dark. They get grumpy if they're woken up from their afternoon beauty sleep and may be more apt to bite if disturbed. If you are usually free in the day, you might want to consider a more diurnal animal. However, if you are relatively free in the evenings, this arrangement should suit you fine. ALthough there have been cases of syrians living well together, it is not advisable to take the risk, especially if you are a new hamster owner.
