Gerbils- varying ages

I have (3) male gerbils that are 3 months old as of November 17th. There are (2) with black fur and (1) with yellow-ish fur. I also have (4) other gerbils who are 2 months old as of December 22nd- almost Christmas babies :) Two are female and two are male. The (2) females and one male gerbil are golden in color with black fur growing in everywhere. The other male is just golden color- no black. There are also (5) baby male gerbils who are (5) weeks old as of January 26th. (3) are black fur and (2) are the golden color. All (12) gerbils are $15 each.

It is hard to find gerbils at petstores in my area so if you want a gerbil(s) give me a reply. I live in portland/ gresham, Oregon. Gerbils make a great pet because they are more independent; don't need to be babied like some other pets. And they are a desert rodent so their bodies ubsorb the water they ingest more efficiently which means less urine in cage and less smell.

-I am fine if you want gerbil (s) as a feeder
