1. Ok first you MUST look at the hamster's nose. If it is like running nose type, PLEASE don't buy that hamster because it usually depents on its nose to do things.(Although it is partly blind)
2. Next I would advice you to buy your hamster about 2 to 3 weeks old. If you buy hamster 4 weeks and above(which is an adult), you will have a hard time to play with the hamster as it treats you as a stranger.
3. Give your hamster a feeding time or els it will be VERY greedy(but if not try not to put too many food in its bow). And give your hamster its favourite snacks when it did something right.

Ok I' am done with it bye~
