This nursing bottle kit is specially designed for kittens, puppies, and small wild animals that are too young to suckle on their own. The soft, food-grade rubber nipple is bite-resistant, flexible, and does not easily collapse or leak. It’s safe for your pet’s teeth and gentle on the mouth. The bottle is marked with clear measurement lines, helping you monitor milk intake and avoid overfeeding or underfeeding. Nipples come in varied sizes and shapes to match different species and developmental stages. This pet care bottle is fully dishwasher-safe or can be easily cleaned by hand using warm soapy water. Before use, soak the bottle and nipple in warm water, then use the included needle to make a small hole in the nipple. Once the bottle is gently squeezed, the milk flows out smoothly for feeding.
