How do you folks determine whether your f/t feeders are good or bad? I just went to thaw Magnus' prey and it began bleeding from the nose as it thawed through. It doesn't happen often, but I feel uncomfortable with it, because of the insinuations behind it-- euthanized under stress/inhumanely, or a potential RI that it passed with. I guess it's a personal comfort level, because I tossed it; just didn't feel comfortable feeding it. Had another mouse actually fall apart while he was swallowing once too, a traumatic experience for all involved. (Fortunately it didn't seem to affect him negatively, just a bigger poo than usual that week.)

What are your indicators that a prey item is no good?
