I got a snake from Petsmart Friday, it is Monday and I just tried feeding him. I tried 1 F/T small mice. I put in a warm cup of water for 45 minutes and tried to feed. When I first tried it took he/she about 15 seconds to strike and he struck the middle and held on for a minute or 2 and then let go so I tried again and the same thing happened. Then I tried for a 3rd time and he wouldn't try at all to strike. I would dangle it around for 5 minutes and he did nothing. He is less than a year old probably 6 months. His temps are for the warm 88-92 and for the cold 76-80. He is in a 6 qt tub with under tank heaters and a thermostat.
