Rabbits, no. Humans, BIG TIME. There's a story in my family about an unfortunate accident involving a case of, um, mistaken identity and a very large batch of homemade vegetable soup (tulip bulbs in place of elephant garlic - an easy error to make, especially when they're right next to each other in the garage). The shorthand version is that about 25 quarts of soup, plus another 20 quarts of spaghetti sauce, had to be dumped.
They still cringe about it... repeated consumption of tulip bulbs, even in small quantities, will result in the eater being first a bit queasy, then seriously unwell, and finally most sincerely dead.
