Thanks so much for the response on the gas anesthesia! Fortunately, Jewel escaped the surgery by passing the furball, but my other love, Bear, began vomiting yesterday morning and the result is that he has a furball as well. I'll hear more today on how the enzymes have done to break it down. Wish my sweets luck! Thanks for the support Patty! Sincerely, Megan, Jewel, Bear & Chewie (my 16# cat!) -- Megan E. Irvine, U.E.
