What to do with jumbo rats?

...... or see of my local store that i was buying rats from would be interested in store credit.

I would give the store a call and see if they would give you store credit and if so then what condition they would want you to bring it in.
Live or Pre-killed or Frozen do you know how to make a CO2 chamber, (I myself personally would want to try and do a cervical break on a large rat)
But I definitely wouldn't give it in either condition (live,pre-killed, or F/T) to your snakes. It's just too big.

Or you could do like Lord Sorril said and give it pre-killed to the crows/vultures/possums if you got some around cause hey they got to eat too.
