Some quick background on my setup:
20 gallon tank
Temps are normal (82-84 cool, 89-91 hot)
Humidity ~%56
Digital Thermometer + Digital thermocouple
2 identical hides

Pretty standard I think.

Well he hasn't eaten since I bought him 3 months ago. No real stress there, he seems active and healthy and acts like 98% of BPs out there. Well I tried F/T rats, live rats, and F/T mice to no avail. Well yesterday I went and got him a live mouse and he killed it within minutes. . .but that's the end of the story. He looked like he was swallowing it but when I came back 5 mins later, it was just laying on the side of his tank. He just ignored the dead mouse and began his evening routine of trying to escape.

Is this normal.
