Ugh....it kind of drives me crazy that F/T is pushed so hard with some of you. I don't mean to call some of you out....but just saying.I respect that some of you feed F/T...pls respect that some of us feed live. They both have different pros and cons.
Feed him what he will take. Not power feeding! But he should probably have more based on what he weighs. (not sure if you know). He was definetly still hungry. I do not go with the 15% as it seems waaaaaaayyyyyy to small for mine when you work it out. So I go with the widest part of the body. But in your case...if they are small....depending on his size...go with 2 or 3. You might also think about starting a colony...if getting them is unreliable. Where I am at the store is like 40 minutes away so we make the trip once a week....which is fine with me. I get to play w a bunch of reptiles while I am there....lol
One of my snakes that is still under 500 grams will take a jumbo mouse...and two adults. But she is a total pig. After all that she will still look at you like....where is the next one. Egads I know I need to switch to rats but that is just a little scary still to me....lol
And sorry Evil me...I still think it is a myth about feeding in the cage. We have done this since about the third feeding on my first snake.....never had a problem. It is almost like they have a calander in their enclosure somewhere. Saturday comes and they are ready for it.
