the guy said he was feeding an adult mouse but when I went to get crix for my bearded I asked about their feeder mice and they said he sounds to small to be eating adult mice and should be eating hoppers.(its a local pet store which is why Im asking the question here) but the snaked did have an injury to his rectum due to defecating something to large, its all healed now but could the injury be related to too large of a prey item and should I try and go back to hoppers for a bit?
