Licking its lips imperiously, a ginger cat mops up every last morsel of food from its curly whiskers, clearly undaunted by its supper's rather unusual base ingredient -- silkworm pupae. The 15 feline residents of the Mao Thai Thai cat cafe in Taiwan are among volunteer taste testers sampling a new cat food developed by silkworm experts. As well as making use of what was previously just a byproduct of silk production, the scientists say the food eliminates harmful intestinal bacteria -- with the added bonus of reducing the odour of the cats' own byproducts.
