Poor Buddy (and your pocketbook too)! That's interesting, I haven't heard of that happening - but maybe not enough people have tried it here? Hmmm. I wonder...if it the stuff makes Buddy really *like* his water, he drinks too much of it - and that he throws up bc he's drinking too much? Have you noticed him drinking too much or no? Or just the usual amount? Either way though, I suppose it's back to the Petzlife....
