Another myth unless your purposefully tickling the snake after it eats?
In the wild if a snake eats 20 to 30 feet from it's den I don't believe someone comes along and places them gently in their home.
The distance traveled back will result in their repeatedly moving every muscle in their body to get home. This would be far more work than the minute amount of handling one would do after a snake eats, that is unless you tickle your snake on purpose after it eats?
