Thanks for the input regarding this issue. I have now lost a Belem Brazil BCC and am pretty upset. I have had this particular boa for 5 years and have had no issues until he just died suddenly. I am now thinking this is a feeder rodent issue and I may have a bad batch of rodents on my hands. I am definitely cleaning out the chest freezer and ordering all new feeder rodents. What do you guys use for a reliable and clean source for your feeders?

Thanks
