I bought a 09 pinstripe back in august and he would not eat for me at all. It got to the point where it was about 1 1/2 months before he took the first ASF. I don't use anything else other then the ASF's. I looked up BHB's website and watched a snake byte episode on probelm feeders. I tried the method of putting the snake into a small container with the fuzzy rat and no more then an hour later I was pleased to see he was finally eating. Anyways he was was originally on mice but I made the switch and he's been eating the ASF's ever since.
