Crystal, thanks for getting a follow up even if it was bad news.

I think the responses here were polite and appropriate. Urgent 'rescues' a possible exception, no one should go into pet ownership on a whim. In between the suggestions to release the frog there was plenty of advice on how to care for it, which was hopefully heeded to make it's last days were as comfortable as possible. At least until the unfortunate incident you've been hinting at.

I do hope the experience has increased their appreciation for nature and the potentially bad outcomes of taking in animals you aren't prepared to care for.
