When I watch it and took it out of the cage yesterday, my snake would readily flicked it's tounge. When he was curled up on my hand, he was readily flicking his/her tounge and it touched my finger. It was so cool!!! I heard this mean they're smelling things. Is this a good sign of a very healthy snake if he/she is readily flicking the tounge in and out of the cage. I would certainly think that it's very healthy, don't you think? Snake rules!!! And so are tarantulas and frogs, hehe!!!
