Ok so if you take a live rat, put it in with a snake so it can strike, bite squeeze the rat to a slow death and thats humane? But whackin it on the head so it dies immediatlly is not humane? Lol really. You own snakes. Either feed em live or crack em on the head if ya wanna freeze em. I personally breed my own rats and i feed live every week. If i have rats left over from a feeding they go back in the rat racks. I have 12 breeder rat racks and 6 holding racks so with that amount of production i do tend to have surplus from time to time but i usually dont have to freeze cause i sell em to other breeders but if ya have to freeze theres nothin wrong with whackin em and baggin em
