It has to do with the way they're wired: the majority of the time, unless they're in premolt (or have picked up some other unknown cue to go on a fast, as rosehairs in particular will do), they will eat food the instant they find it. They don't understand that we'll always be around to give them food in the future, so they think "oh man I better eat this, I might not see food again for six months!"Thanks for every one's input. While she has always taken the crickets immediately, I did feel like I was feeding her more than was needed.
How big is your blondi?My T's usually just stop eating when they are done. My T. blondi will eat 5 crickets in 1 night but then not eat anything for around 4-5 days. My Avic will only eat 1 cricket at night and then she skips the next feeding or 2. Not sure if thats the correct way to do it but they seem happy and healthy. :?
