Why in the world would anyone intentionally make their frog throw up it's stomach?

I would have freaked out about what you saw but, after reading everyone's posts it seems sort of normal and your little guy seems fine which is happy. I must admit I had the most awful pit in my stomach for you as I read through your first few distressed posts. I'm a paranoid frog owner too - you're not alone!

Glad all is well with your White's.
