All young and healthy males. They are quick and fun. Gerbils makes great pets for kids. They are easily hand tamed and are not nocturnal like many small animals so they are awake and ready to play whenever the kids are. Gerbils LOVE to chew so proper housing is a must. They make short work of plastic habitrail type cages. Must be adopted in same sex pairs. They can be adopted in pairs with their handmade bin type housing for $30. Or $10 a pair if you have proper housing for them. Please do your research on these special animals to make sure they are the right choice for your family.
