“KittySicle Factory” isn’t funny. It’s making light of the animal abuse and the subhumans involved.
In this country it is legal to suck a baby out of its mother’s womb with with a wet/dry vac and we also euthanize thousands upon thousands of domestic animals per day.
In all of that, I am not sure which is the best way to euthanize a kitten, but freezers, throat slits, needles or gas all has the same results.
For us, the best answer is controlling the pet populations and there is where we are at fault.
