Pinkie

I'm a pink female cat who can change into a human girl with pink hair, so the picture shows me in both forms. You (m/f) bring me home from the cat refuge because nobody else wants such a weird looking cat. You look after me and love me but after you've gone to bed, I change into a human girl. One night you come down in your pjs for a glass of milk and find me in the kitchen in human girl form.
