How to be a good hamster owner (for kids )
Get a large enough cage.
Perhaps the most important item you'll need is a small cage or terrarium. This way, your little friend will have a safe place to play.
Your terrarium should be greater than 15 inches long by 12 inches wide and 15 inches high (38 by 30 by 38 cm). If you have a lot of toys or places for your hamster to climb and explore, though, you may need a bigger cage.
