I thought you were feeding mice too, Ashley. I know I wouldn't be caught dead bringing unquarantined rats into my home full of 30 pet rats. I did once and lost 10 of my heart-rats in a week from strep-based pneumonia(I had a culture done on the lung fluid of one of the deceased)..

I promise, Balls do just fine on mice their entire lives. Boas absolutely do wonderfully with f/t rats their entire lives(mine is 8ft long, so she's on 2.5lb rabbits every 3-4 weeks).

I know you have pet rats that you care about, and wouldn't want to risk their health just because someone told you that one prey item was better than the other.
