I was also asked by my grandma, can I feed it lettuce instead? ...

Funny things is, my grandma HATES it that I have snakes. I had some frozen pinkies in the freezer, and she's like "You can't have them in there!". And I asked "Why?" and she said "'Cause I don't like the way they are killed!". And I laughed and I said "Uh, hello?! You got like 20 pounds of meat ranging from chicken, steaks and ribs, so why is it ok that you can contribute to their terrible death, yet the way mother nature uses mice as a way to feed snakes, is wrong?". She just replied "I hate the way they are killed". So me being me, I got as graphic as I could and explained in detail the death of a cow. Yet she still doesn't like the way snake eat their pray ... Go figure huh?
