Is it normal...free kittens!
So...
I keep an eye on the classifieds for free kittens.
I have a pet boa-constrictor named Reggie. They provide a food source for him, it helps control the population of an invasive species, and gives the kittens a home...if short-lived. I take very good care of them before I feed them to Reggie.
I already know that this is going to get a backlash, but seriously...what's the difference between that and any other snake food? Why would you hate snakes so much that you'd deny his next meal?
