When does a guinea pig stop growing? and what is the size of an average guinea pig?

Answer 1

they wont grow when they're over one year old.

and girls are about 10-12cm

and boys are about 15cm

Answer 2

They stop growing when they're around a year old, but then they usually gain some weight.

They're usually 8-10" long and weigh about 2 lbs.

Answer 3

Im not sure when they will stop growing but i know that they are about the size of a shoe...i know thats no help but i read it in a book =)

Answer 4

It will stop growing when it's about 10 months old, but a lot of people say theirs have kept growing long after. That's usually just them getting fat, though. It should grow to be 9-12 inches, kinda like the size of one of those smallish nerf footballs... just don't use it as one! haha
