mine are about 4/5 months and still growing, think it might be around 8 months when they become adult but not sure
 
Thanks alot for the reply, they are in a nero 3 at the moment and dont want to get nero 4 until they are fully grown. Just found this on a guinea website!

"The guinea pig increases in weight and length until about 15 months - after which, weight changes are secondary to loss or gain in stored body fat.

I found that my guinea pigs had most of their size when about one year old, with one last growth spurt at about 13-15 months.

At about the same time they will settle down to adult life and become gradually quieter and a bit less energetic and playful.

Enjoy your youngsters - it's the most wonderful time!
 
Wow, I didn't realise they kept growing for that long :))
