Seven inches
as long as its not to big and not to small
The best kind would be a Syrian hamster. They live 1-5 years and are very playful.
The best hamsters irecommend are the Syrian hamster, the teddy bear hamsters, or the winter white hamsters. the Syrian hamster is a large hamster usually growing 4 to 5 inches. They are great first hamsters. the teddy hamsters are often furry and similar to the Syrian but grow to 3 to 5 inches. The winter white hamsters and playful fun and easygoing and grow 3 to 5 inches.
If the daddy hamster is a Syrian, seperate them immediately. But unless the daddy is a dwarf hamster, you can just leave it there as most of them are good fathers. But it's best to seperate them.
Try a Syrian hamster. This type of hamster is the biggest and hard to lose. They are very friendly. They also come in different fur patterns. Syrian types are: Panda bear teddy bear golden fancy longhair shorthair
The best place to get any hamster is at a reputable pet store such as PetsMart. You never know if a hamster will be nice until you get it home.
Personal opinion but I would say a syrian is rather easy to care for.
You don't need one, but it is best to have one. Hamster balls enable hamsters to get a session of good excersise. Although most hamster cages have wheels which provides excersise hamster balls enable you to controll the amount of excersise a hamster gets.
To be honest I don't think it really matters. I always had clear because I think that it is better for the hamster to see where the are going.
syrian hamsters are best i would say but they are known to bite. although mine has never bitten me.
Save the hamster food
I dont know if which is the best kind of hamster but it is not the syrian hamsters. They are the worst. I have a Teddy Bear hamster and he has not bit me since I got him. (I have had him for 2 months)
