Changing Spaces

[ckhs]

I am a new rat parent of about 6 months.I have four adorable females who are at long last healthy..I hope.I have had them in my living room for almost the entire time but have just moved them to my room where it is much brighter during the day, also i like to keep the sliding door open for fresh air at night.I am wondering if the light will interfer with there normal sleep habits also if the fresh air will give them a chill and bring on yet another bout with the respitory issues.I will add that i live in Arizona so it does not get to cold.All thoughts greatly appreciated.
THANKS..ckhs
