To help a kitten feel comfortable and secure during the bathing process, start by introducing it to water gradually. Use a calm, soothing voice to reassure the kitten throughout the bath. Ensure the water is lukewarm, not hot or cold, to avoid shock. Place a rubber mat in the sink or tub to prevent slipping, which can cause panic. Keep the bathing sessions short and reward the kitten with treats and praise afterward. Familiarizing your kitten with the bathing process early on can significantly reduce stress.
