First of all, he said small/MEDIUM rat. Every snake is different. For some, that would not be enough. For others, that would be a good feeding schedule. A lot of people feed their adult snakes once per month.
Also, if you think I'm "griping" you're sorely wrong. I am stating my opinion. If you have a problem with that, go to another thread. I wasn't being mean or rude. This was a completely friendly debate.
