should I?

Question
I have 2 guinnies,1 is 2 years old and the other is almost6-7 months old now.I have a 15x37 cage. I think it's a little small,but is it also necessary to get a bigger cage?And why?Thank you!!

Answer
It's necessary to get a bigger cage because guinea pigs need room to roam and play. A smaller cage poses problems because there is not enough room for two guinea pigs to play and exercise and they can actually become quite unhappy in a small cage. A small cage also poses problems with guinea pigs getting along.
