To train a kitten to use a litter tray effectively, start by placing the tray in a quiet, accessible location. Use a litter that the kitten prefers and keep the tray clean. Encourage the kitten to use the tray by placing them in it after meals or naps. Reward the kitten with treats or praise when they use the tray correctly. Be patient and consistent with training to help the kitten develop good litter box habits.
