Guinea Pig Question

March 15th, 2008, 01:50 AM
When do guinea pig reach adulthood/full grown? Ours will be 5 month old on March 31...My boyfriend says they're full grown and I say they're not. To me their faces look like they still have growing to do...

Who right? Heheh you better say me :D

According to this site ( ) it is six months :shrug: ....

They will reach sexual maturity at about 3-4 months, but full adulthood is at about 6 months.

For the most part your Guinea pig is about done growing.It will "fill out" abit more though.Do you know how much your pig weighs?They can hit 3 pounds and sometimes upwards of that.
