Why does my hamster keep biting me? How do I stop the biting?

Congratulations on your new hamster. I am linking an article here which gives an in depth discussion on methods to try to tame your hamster: http://www.yourpethamster.com/care/taming The key is having patience and persistence. Working at this several times a day and taking it slow to build up your hamster's trust in you. Best of luck to you and Charlie!

Thanks for reaching out about Princess and including photos. Hamsters can be touch, socially. Continued de-sensitization might help, but also by looking at the photos, your access point seems to always be from above. A large human hand coming down to grab from above can be scary. If you use a cup to scoop her up (gently) and then place her on a flat surface, is she still aggressive? Maybe she is defensive of her enclosure, and might be more timid when out. Lastly, having her spayed might decrease aggressive, but a big surgical procedure. Good luck.

Unfortunately, some hamsters are more fearful and aggressive than others. This is just their personality. I would try to offer him daily treats but avoid touching him for awhile. Over time, slowly just try to pet him but do not antagonize him or pick him up. If he lets you pet him, give him another treat. Hopefully, over time, he will begin to warm up to you but unfortunately, not all do.

What you are describing is normal behavior for a hamster. In fact, I think it says a lot about his trust for you that he lets you hold him and does not bite. Many hamsters are too fearful to ever let their owners handle them regularly. Clout is probably just very curious of the new smells around him when you are holding him. It sounds like you have done a good job training him and that he trusts you so you’ve done well with him so far! I hope this helps. Let us know if you have any additional questions. Best of luck.

While hamsters are great pets, and super cute, they can be aggressive by nature because they are a prey species, particularly males. I recommend letting Sammy get used to you by first putting a hand in his cage and letting him come to you. Once you feel he is comfortable with your hand in the cage, you can try gently picking him up, making sure to always support his back end.

Thank you for using Petco Pet Education Center, formerly Petcoach! Hamsters are pretty aggressive naturally, as they are commonly a nocturnal prey species. They also make burrows and nests, so it may be why Eggnog is destroying his toys. You may have to move very slowly with Eggnog, offering treats through the cage and even just approaching slowly and standing near his cage to start. I hope this helps!

Show this to your sister: Check him thoroughly for injuries, or other abnormalities. Watch him when he eats. If his eating style has changed, he may have a problem in his mouth or with his teeth Most of the time hamsters chew the cage because of boredom, attention-seeking behavior, managing teeth growth, and the simple fun of chewing. Does he have a hamster wheel or an exercise ball? If not, those can relieve boredom. Give him some apple or birch twigs, Willow works too,dog biscuits, carrots to gnaw on. A hard dog treat helps with keeping teeth healthy.  Spend more time with him. Let your hamster crawl around on top of you while you lie on the floor. Hamsters love to explore, and once he has developed a trust in you he will want to climb all over you. Let him sleep during the day. Hamsters are nocturnal, which means they sleep during the day and are awake and active at night. Waking him up during the day, may cause him irritation. Interrupting his natural sleep schedule could lead to further undesirable behavior.  Check the size of his cage. As a general rule of thumb hamsters need at least a cubic foot of space. If your cage is smaller than that, he will need a bigger cage. Change the furniture in his cage around a bit to make it more interesting for him to explore. A cardboard tube from a roll of paper towel or toilet paper makes an excellent chew toy for hamsters and he should like to use it to hide and play in it. All this may help avoid biting , whether it is cage biting or biting your fingers. This is likely not a medical problem, unless you find an injury or you find that he is not chewing or eating properly or you think he may be in pain. And, unfortunately, sometimes Hamsters can turn into little bite machines. So if your hamster has plenty to chew on as described above, and the cage biting does not stop, you should move him into a glass aquarium, so he cannot keep up chewing bars and ruining his teeth. Be patient, it will take time. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
