Sorry, but why are you taking them to a petshop?

The cycle will just be started over again. They won't split up the litter and the females will become pregnant.

I agree with luckies, put an ad in the paper or on the internet. I find that it works best when you put them in the paper. Tikeyas_mom got hundreds of calls that way for her baby hammies.

Please reconsider taking them there, everyone is always saying how pet shops are evil, and so I just can't bear to hear of little baby ratties going there
