Cute boys! Barnum is an agouti and Bailey looks like an argente cream (in case you wanted to know)
Yeah, some people say with giving lots of greens and whatnot they don't need water but I like to provide it as well. Have you tried giving them mealworms as a treat.. some of mine go CRAZY for them.
Marisa, they are very non-smelly. I have my boys in a 29 gallon and fill it halfway with aspen and hay and they make a giant ant-farm out of it all and I don't clean it but once a month. They seriously have an underground castle made of wood buried in there with multiple passages leading to it...My boys are weird though since they prefer digging to a running wheel so I gave them a tall tank with the ton of bedding. For my girls that have only a few inches of bedding I clean it every 2 weeks. They LOVE the running wheel and are not so keen on digging like my boys.
My hamster, on the other hand, I have to clean almost twice a week and can still usually smell her.
Just like chinchillas, gerbils benefit from regular sand baths and mine have always seemed to enjoy eating some of the sand, so I don't know if there is some mineral they get from it that they don't readily get in their food, but they always taste it. I love how curious and clean gerbils are in comparison to other rodents. I've had about every rodent, and I like them all, but gerbils take the cake.
I've always wanted some bushy tailed jirds to keep in a desert-like terrarium. Maybe someday
