Meat-eater against Ball Python

I think if you drop a few live rats off at her place and they invade her house she will invite some snakes over real quick. Maybe that is alittle drastic,but still an option.

I don't understand how she can disagree with nature.

I do not eat red meat. i used to be a vegan like my fiance until i started working out a alot and to bulk up to the weight im at its easier to eat fish, chicken, ect.. And i am not against feeding rodents to snakes. Even live (i always feed f/t though). A snake cant change its diet and adjust but we can. Its a big difference. If she was at first willing to get the snake its diet should not turn her off to unless shes squemish at the look of a dead or live mice.

Sounds to me like she's a couple of meaty ham sandwiches short of a picnic. Trying to argue against her illogical outlook is going to be about as successful as, I don't know, something unsuccessful.
Give up while you're still sane (I presume you're sane, anyway) and be glad you get to have snakes.
