i have talked to many people that buy there rats from the same place i do. there are a few that will buy a huge meal for there snake and only feed them about once every 4-5 weeks. i have tried to tell them that a good sized meal ever 7 days is ideal but they alloways say i have had this snake for 5 years and it is fine. wich is true if it is working for them then so be it. just dont ask me to condone it.
