How do I know if my frog is in going in to estivation?

[GrifTheGreat]

what happens if you never let your frog go into estivation?
is it absolutely necessary?

If you intend to breed your frogs then it is a must. They do not. Have to go through Aestivation as a necessity otherwise. I will say that it adds to their lifespan if they are put through Aestivation. Atleast everything I've read claimes that it adds to their life. They can live very long happy lives without it as long as you. Maintain the correct conditions within their home. Some will go under on their own without a climate change to turn on that instict.
