How to Train Your Hamster

1. When you bring your hamster home, leave it alone for a couple of days so he/she can get comfortable with its new habitat. This will teach it that you won't push the hamster into something it doesn't want to do. Also, make sure that your hamster's food dish is filled when you put it in the cage. Don't leave the hamster in his ball (if you have one) too long, or he/she might go to the bathroom in the ball and it will go through the cracks! 
2. Get them use to the sound of your voice by reading a book or singing a song to them. This will let them feel comfortable and secure when they hear your voice. 
3. Put a sunflower seed or a hamster treat in your hand and then lay it flat in the cage. Wait patiently for your hamster to climb on your hand and then take the treat, do this for about an hour. Your hamster, however, might grab your finger instead and bite it. Now this time, when the hamster climbs on your palm, slowly lift him out of the cage and stroke his/her fur. This teaches him that you love him/her and he/she can trust you. Eventually he will climb on your hand and will be waiting for you to pick him/her up. 
4. Teach your hamster some tricks. This will not only give you a bond, but it will make your hamster respond to you better. Start simply with "stand". Hold a treat over his head and wait for him to stand on two legs. Say "stand" over and over. He will get on two feet and take the treat. After a while when you say "stand," he/she will do it on it's own. Don't forget to reward him or her! 
5. You can do the same thing with other tricks like "paw," only put the treat in front so he will put a paw forward to get it 
6. For "turn" or "roll over," put the treat on his back side so he will turn around to get it. Then do the same thing as "stand". Say it and repeat it. Don't use treats until after the trick has been performed and now you have a trained hamster! 
7. Train him about what not to do. If he/she chews on something he/she not supposed to, say assertively "No". Every time he stops when you ask, give him a treat or love. Whenever your hamster does what you ask, give him/her a reward! Try not to make the reward a treat all the time because too many treats is a bad thing! 
8. If you want to be a good owner then get a box a little bigger than the size of a sticky note then fill it with sand have your bedding be level with the box so he will be able to climb onto it then they will be able to dig and will love you for it. 
9. Try Jump Put a treat up above the hamster and go up with the treat when she is standing say jump again and again 
10. Try giving the hamster a carrot as a treat. Most hamsters like carrots. (Some hamsters even like Honey Nut Cheerios! But regular Cheerios are fine, too. If you prefer, anyway.) Do not give carrots to your hamster often, but only once in a while. Your hamster will appreciate a new treat.
