Use a mild, baby-safe shampoo or a special pet shampoo suitable for monkeys. Avoid getting water or soap in its eyes, ears, or nose. Use a soft cloth or sponge to clean its fur gently. Rinse thoroughly with clean, lukewarm water to remove all soap residue.
After the bath, wrap the baby monkey in a warm, soft towel and gently pat it dry. Keep it in a warm area to prevent chills. Brush or comb its fur lightly if necessary. Offer comfort and reassurance throughout the process to keep it calm and stress-free.
