Members of a feral cat colony at Old Puunene School escort Department of Education special education physical therapist Linda Griffith to their feeding area Tuesday afternoon. Griffith knows all 32 cats in the colony by name, and she has helped trap 28 of them so they could be spayed or neutered. She said the last four are proving a challenge because they not only shy away from the trap, but their buddies, ones who have been trapped before, are usually the first inside to gobble down the food left as bait. Griffith said her real job as a physical therapist for handicapped students also has its challenges. "The rewards are slow, but when they come they are sweet," she said. "Especially when a child learns to walk for the first time, that's amazing."
