The Times noted adults, too, enjoyed the exhibit, which is based on a book in the Grossology series by Sylvia Branzei. Michael Ma of San Francisco made falling-bomb sounds as he pushed a plastic-encased hairball through the digestive tract of a cat illustration. "I can't wait 'til we have a kid," Michael Ma told his wife Stephanie.
