Nikita Snape was the familiar of Severus Snape. A black-furred Kneazle with emerald-green eyes, she was fiercely protective of her wizard. She chose Severus when she was a kit at the Magical Menagerie before his first year.
She became a mother to four hybrid kittens later in her life. The father, Alan Conway's familiar, Machiavelli, introduced the litter to Severus by picking up the firstborn kitten in his mouth, carrying it over and gently laying it in the Slytherin's lap. The smallest of the litter, the small yellow and black tabby was given the name Aeron.
