I dont understand whats the big deal about a snake getting bit by a rodent. Most of the time is not even a big bite or scratch. We as pet owners/keepers are the ones who exagerate and make a big deal out of it.
If snakes could be so easily harmed or killed by a rodent, we wouldn't have any snakes today, because they would have been extinct A LOOOOOOOOG time ago... Their skin has evolve to deal with those kinda injuries and many other things.
I think keeping frozen rats is gross.
I rather feed and keep a live rat/feeder and clean after it than keep dead frozen rats in the freezer and even more gross to watch them defrost.
Rodents are pretty amazing animals too, just watching them is amazing. I rather see a live one and interact with it than seeing a frozen dead one.
It's a personal choice... If you feed F/T is fine, but dont go around pushing it into people. You are what you eat, and what you eat is usualy in the fridge/freezer!
