Once a
kitten is weaned, his sucking days are over—but not always. Sometimes older kittens, and even adult cats, can be seen sucking on another cat’s teat, on a human’s finger or on a piece of cloth. It does no harm, though it strikes the owner as peculiar. The author has known of a few cases where a fully grown cat would “nurse” on the teat of a dog—in some cases, a spayed dog that had never produced a drop of
milk in her life. In every case it appeared that both the cat and dog enjoyed the arrangement.
