I am fostering a momkitty and her litter of five kittens for the Connecticut Humane Society. The foster momcat, Linda, is weaning the five kittens. All morning she has been sitting on a windowsill. Every time a kitten comes up onto the sill, she takes them by the scruff of the neck, and drops them over the edge and on to the floor. They seem to be getting the message. What a smart mommy!
