Excellent for use with fawns. Pritchard Nipples are made of a soft, red latex that closely resemble the ewe’s teat. Lambs and kids quickly learn to nurse when using the Pritchard Nipple. Nipples screw easily onto any standard soda bottle. Threading on the cap prevents leakage. A special flutter valve prevents air intake. The tip of the nipple is cut off to increase milk flow. Wash with warm, soapy water.
