I am deeply, deeply disturbed by this post. A frog will not survive two weeks without food and fresh water. drastic temperature changes and stress and also deadly. that is what killed your previous frog.

Is there really NO ONE who can take care of your frog while you are gone?? Where are you located? There may be someone one this forum willing to take your frog. When you have a pet, it is your responsibility to take care of it. You wouldn't leave a dog alone in hot house for two weeks. At least I sincerely hope not. Show the same consideration to this frog. It is a living creature.
