I have a 145g 3mo and roughly 16-20" long new BP. I got him in a week ago, and has settled in and considering he hasn't excreted, he hasn't eaten in a good bit. He's hungry.
So I got him a mouse today. An adult, live mouse; I used the feeding chart to determine this and everything, and the women at the pet store, after having seen Zerok before, suggested that size for him. After I got Zerok I asked the supplier what he had been feeding. They said, he eats mice or rats and they feed live. So I figure... no problem right? Wrong.

I put the mouse in. Zerok is tense and smelling the air. The mouse walks right by... multiple times. Zerok makes two "lunges"- enough to scare the mouse, but no attempt to strike. He knows it's food. Yet he doesn't seem to know what to do. A third strike- only air. Mouse runs to the other side. When it comes back, Zerok makes a fourth attempt a little later- not only does he miss, but he gets a mouth FULL of soil... I had to hold his jaws open and scrape it out to the best of my ability, as it had coagulated with the spit in his mouth.
I put him back in, he watches the mouse for a while. It is literally hopping over him, digging in the substrate, climbing his plant. And Zerok... goes into his hide. Leaving this life rodent to explore.

What do I do? I've never had this problem. My adult female has ALWAYS killed, and immediately. Now I have this live mouse on my hands... and I know he's hungry :/ Help?
