Sometimes my hamster is so aggressive and it's not always clear why. I decided to have a look what makes hamsters aggressive, whether this is normal behaviour and what to do about it. Let's dive in. Why is my hamster so aggressive? Hamsters are not naturally aggressive. If your hamster is aggressive then it could one of three things: you are disrupting his natural sleep schedule and try to interact at the wrong times your hamster is not tamed enough for him to be happy for you to handle him his living conditions are inadequate, and your hamster suffers from something called cage rage Why is my hamster so aggressive? If you have a tame hamster but you are trying to interact at the wrong times, you might get a nip every so often. Hamsters really don’t like to be woken up and unfortunately most hamsters sleep the larger part of the day. They also don’t like to be petted when eating. Find the right time to pet your hamster and you will see an improvement straight away. If your hamster is not tame, it will take some time before you can pet your hamster without being bitten. Remember that this ‘aggression’ is just fear. You will need to win your hamster over and make it understand that you are kind and caring, and the only way to do this is by spending time with your hamster. If your hamster has cage rage, then you need to change their living space right away before he hurts himself or dies. Cage rage is enormously stressful for your hamster, and it can both kill him by accident or because of stress related illness. Most hamsters will settle once their environment is more suitable and they’ll go back to being a great loving pet. Are hamsters aggressive to humans? Hamsters are not normally aggressive animals. When they are not happy, they will bite as this is their only defense mechanism. And unbeknown to you, your hamster could actually be unhappy and show it by ‘being aggressive’. When your hamster is not tame: If you’ve never been able to handle or pet your hamster, then your hamster is not used to you, and you will need to spend time taming your hamster if you want to be able to pet him. Your hamster will need to get used to having you around and learn that you are no threat. You can only do this by spending time with your hamster every day several times. Below is more information on how to do this. Are your hamsters living conditions suitable? Many hamster cages are unsuitable for hamsters to live in. This is especially true for the fancy plastic cages with lots of plastic tubes sticking out, with little to no floor space. Hamsters are very active creatures and need floor space to run around and investigate. Too little space makes your hamster super stressed. Invest in a larger cage. Especially syrian hamsters are typically housed in a cage too small for them. It could also be that you have more than one hamster in a cage, or you have two cages next to each other. While dwarf hamsters are fine to be together in a cage with other dwarf hamsters as they aren’t very territorial, syrian hamsters are super territorial and will become stressed just by having a hamster in a cage next to them.

Your hamster is tame when you can pick him up without any problems and he’s happy to be petted. He might eat snacks out of your hand or cuddles up when you hold him. There are times when even the tamest hamster is unhappy to be picked up. At sleep time, hamsters are notoriously grumpy, and you can expect a nip when you wake your hamster up to be petted.

When you first bring your hamster home you need to give him some space to get used to the new living space, and the sounds and smells of your home. This process can take weeks and the idea is that you get used to each other in this time. Lots of talking and singing to your hamster in these first weeks means that your hamster gets used to having you around. Putting a cloth with your scent in his cage means he gets used to your smell and is less likely to be scared once you start being close to the cage often Once your hamster knows your voice and scent it’s time to put your hand in the cage and just leave it there for your hamster to investigate. Maybe put a treat on your hand to entice your hamster to come closer. The next step would be to stroke him over his back softly and see if he allows this. Once you have established a bond and your hamster knows you are no treat, you can try to pick up your hamster. Your hamster can seem aggressive because he bites you when you try to pick him up or even as soon as you put your hand in the cage. But it's very likely your hamster is scared rather than aggressive. Hamsters need to be tamed before they become the cuddly pets we’ve come to love. If at any time your hamster doesn’t seem happy with the new step, go back one and give it some more time. Importantly stay consistent, interact with your hamster often and don’t ever make any sudden movements as this will scare your hamster for sure. Are hamsters dangerous to humans?
