Need some help here please. I recently switched over from f/t mice to f/t rats. Fed my BP his 1st rat pup on Weds night. He's a shy eater so I had to let it in the cage and come back the next day to find it gone. Well I left for the weekend and just returned tonight (sunday) and found him laying next to a regurgitated rat. The smell was intoxicating and I was mortified. It took me several minutes to figure out how I was going to get him out of the cage while he sat next to the rat.

For info, he's about 250-250 grams and this was his 1st rat pup. What could be some of the reasons be this happened and what should I do going forward? I think I remember reading that I should hold off feeding him for something like two weeks. Should I try another rat pup again or revert back to a mouse?

Any ideas how to get the smell out of the cage? I stripped everything out and cleaned it w/ some chlorhexadine but that only does so much w/ the trapped air in the pvc enclosure.
