Nursey

Hildy loves her "Nursey", which is actually one of Megan's old sweaters. It is common for kittens who leave their mothers too early to want to suck incessantly on wool. It's very similar to the mother's underbelly, and has the same oil in it ((lanolin) that a cat's coat naturally has. This behavior may even carry on when she is an adult cat.
