I have read and heard that venomous snakes can have a procedure done to remove the venom glands from them.......making them all the more easier to handle. I also understand that sometimes all the venom cannot be removed.

Here is my question. If a venomous snake has their venom glands removed how does it kill it's prey? I know some venomous snakes like a rattle snake will strike and release it's prey and then eat it after it dies. A venomous snake like a cobra will strike and hold the prey while it is pumping venom until the prey dies.

Do these keepers just feed frozen/thawed to their animals that do not have venom glands? I am just wondering how the snakes eat that have their venom glands removed. For whatever reason I have just been curious about this. I have no intention of ever owning a venomous animal but was curious nonetheless.
