I have a corn snake for over 11 years. Since I got him, I've always fed live with no problems. About a year ago, I bought a boa and found this site as well as redtailboa.com. When I learned about the dangers of feeding live, I switched to f/t. The corn never showed a problem. Recently he started refusing the F/T. At first I thought because I thawed the F/T out in the same water as my boa's rat pups (he refuses to eat rats). But after trying twice more defrosting the mice separately, I decided to try live. With no hesitation, he constricted and ate his first live mouse in over a year. Seemed a little unusual, but what ever it takes to make his highness happy.
