It is really hard to tell. If you bring your gerbils to a pet store a worker might be able to tell you the aproxoment age. Visit my site for more info! www.gerbls1234.webs.com
Well, when they are born you know they're young. and when the die you know they are old unless you murder them.
The gerbils have to be 7 weeks old to be able to sell them.
most gerbils have to be 3 weeks or older
Yes. I have a friend and she has gerbils that are over one year old. They have had babies. In a gerbils lifespan gerbils have around 15 litters of babies.
Yes.
Gerbils will NOT swim they will drown. They are native to the desert and they don't know how to swim.
3 years old
gerbils mostly live in pairs or small groups so it depends on the size of the cage and if the gerbils know each other
No way. They'll start attacking each other. =/
http://en.allexperts.com/q/Gerbils-Hamsters-2005/ I don't know why this is happening, even though I do know a lot about them (I am not calling myself an expert) but go to that link, and if you can't find anything helpful, try asking the question youself. I hope you find it really hopeful, and that the gerbils end up okay.
you never know unless you feel them inside your gerbils stomach wich can be very dangerous for the mother and the babies !!!!
Gerbils really don't care about the color of the other gerbils in the tank with them, they really care about personality. For all we know, they could be color blind.
