I know that everyone has their own idea on how to feed, but I personally do not like to feed my reptiles on a specific cycle. I prefer to do it haphazardly, obviously still making sure they are always looked after and fed properly. But not every saturday at 9pm, or whatever. I personally think that this is better as then the herps come looking for food, and try to "hunt" some. In the wild they are not fed once a week, more likely once every 2 to once every month. I would never not feed a herp if he needed it, but the fact that snakes can often go 6-8 months without feeding must surely say that they do not require being fed on a particular cycle.
I am not having a go at anyone, as I don't think feeding on a cycle is a bad thing (especially if you have a large collection. Then it has to be done to get them all fed!!), this is just a personal preference.
