Hamsters are affordable to purchase and keep - but, this is relative. However, no matter what, they are one of the most inexpensive pets to keep. Pieces of fresh vegetable that is not used for cooking can also be given and this will supplement food you buy. In a nutshell, don't make the mistake of concentrating on getting a hamster at a good price and neglecting all the other needs. This is usually what happens with new pet owners.
Hamsters are favorites with children - but they can bite and their bites can draw blood.
Each hamster is different and some may never bite especially if they are tamed by you. There are some hamsters that do have a tendency to bite especially if they are not handled by the pet shop owners. This means a hamster that you cannot interact with. Others may not want to take the hamster in either. Most of the time, very sick hamsters have little chance of survival.
