Abstract: An inflatable, multi-purpose whelping system has an inflatable pen with an inflatable, peripheral side wall attached to a bottom. A liner that drapes the interior surfaces of the inflatable pen is fastened to the pen. The inflatable, peripheral side wall comprises a plurality of discretely inflatable segments disposed one atop another to allow for height-adjustment of the inflatable, peripheral side wall. The liner has a band biasing a peripheral portion of the liner into a wall seam between adjacent segments of the inflatable, peripheral side wall. The inflatable, multi-purpose whelping system includes a feeder. A method and a kit for preparing the inflatable multi-purpose whelping system are also disclosed.
