How old do the guinea pigs...

Question
How old do the guinea pigs have to be before you and take them away from there mom.

Answer
Hi Cheryl.  Anywhere from 4-6 weeks.  If they look big and healthy at 4 weeks, you can wean them off.  Or, if you notice they are no longer nursing.  If they seem smaller and you want them to spend more time with mom, 6 weeks might be the better option.  Personally I go with the 4 weeks, it seems plenty except in special cases where the litter was very large (5 or more) or the babies were especially small (under 100 grams).
