Playtime outside the cage

We've had our chins for about 2 years now and we have recently gotten very busy. We used to be able to let our chins out almost ever night for play time, but now we are down to maybe 2 nights a week...They have the chinchilla mansion cage so they have a lot of room to jump and climb, and a lot of toys to chew on.

We are by no means neglecting them. We jus didn't know if it mattered, the amount of time they are let out of the cage. I guess we feel bad because they were used to being out so much.
