hold the pup to a hard surface firmly with a screwdriver and quickly give its tail a good hard tug. should break its neck and kill it instantly.
or
give it a good whack right behind its head with the handle of the screwdriver. you might have to hit it a few times...
these are the two ways i kill feeders.. the way i tell when its dead is its bowels and bladder will release and it will kick its back legs a few times.
yea the first time is the hardest.. after that its just another mouse.. or rat.. dave
