I agree with patience. I have successfully converted 13 ball pythons (babies to adults). I thaw in a plastic bag in luke warm water then right before I feed I increase the temp of the water. I offer with a long hemostat that I have previously used to feed the live. I have found that they eat better if they are not scared by the hemostats. I will present the rodents head to the ball. Sometimes they appear to take the prey better if I start near their head and slowly move away. Never touch them with it. If they dont eat that meal I will wait until the next feeding 1 week later. If they dont eat the second week I will give them live. This 2 week routine seems to work well. Im not a fan of starving them until they eat. I like to keep the GI tract as healthy as I can and starvation does not help with this. This routine seems to work well for me but Im sure others have their tricks as well. I have tried warm chicken broth in the past and that seemed to work well also. I have not yet "brained" the prey. I have heard it works well but I have been so successful with this routine that I havent had to go that far yet. Hope my routine helps and dont give up if it takes a while.
