Feed in the enclosure as I and many others think that it is a old wise tale that it makes them cage aggressive. This is easier to feed in the enclosure and less messy ....plus it doesnt stress the snake out so much.

If you are changing to rats...here is a couple of pointers as sometimes they will not switch. Have the ppl put some mouse bedding and mouse droppings in with the rats. If she will not take the rat, (and this sounds gross but works) rub some mouse droppings on the rat. Sometimes some snakes can be finiky about taking a rat. Just continue to offer and rub some doo do on it. lol

As someone else stated you might also consider getting an under the tank heater (UTH). You will also need a thermostat to manage this. Some stores will tell you that you do not.....but you totally do. This will help in keeping up your humidity as well as it will be better for your snake. They use belly heat to digest. You can look at Herpstat or Reptile Basics for thermostats. I personally stay away from zoo med products as I do not find them reliable. That is just me though......
