Bob, cat No. 2, is a 1 1/2-year old, orange-and-white domestic shorthair. Bob was "quite thin" when he was brought to the Maui Humane Society's Puunene shelter on April 8, but since then he has gained weight to a healthy 11 pounds. Bob has been neutered and gets along well with other cats. Shelter staff said he takes the new kittens under his wing to "show them the ropes."
