I want a gerbil can you guys help with my little questions?

I've had gerbils before. One would do back flips in it cage(: but you can get tumors around 2 years. Mine did. There very sweet and mine loved seeds and would take them right out of my hand. they eat the same as hamsters. Get them a cage they can have fun in and make sure theres enough room so they can make burrows. Make sure they have a wheel as well. I also had a ball for mine and he loved it! Also you can get a good cage from petsmart or petco.
