Well, girls are very active...yes. But you have "teenage" girls too. So, they will be pretty spazzy for a while. I have a cage group of girls ranging from 2-6 months...and it's just one big party all the time. Of course, they are the cage group that gives me the most laughs and there's never a dull moment.
Even young boys this age are pretty active and love to popcorn around and such.
It seems to me that you spend a part of their lives wishing they would calm down...then the other part of their lives wishing they were young and energetic again.
The snuggly stage will come much too soon....and then they are elderly
I love both stages...because I adore my snuggle babies...but get such a kick out of the youngsters too.
The more you interact with the girls, the more they will eventually come for snuggle time.
Do you have a woden wheel? This can keep your girls entertained while they are in their cage. I have three in my cage group of 9 girls...they run on them all night long.
