Ok ... so Chloe doesn't have any children of her own. BUT, she does make an awesome kitty pretend mommy!
You can see the wet spot on her leg from where Willow had been "nursing" ... Chloe just lets her do it, and then Willow falls asleep curled up with Chloe. It is too cute!
Willow also "nurses" on Pickles. However, Rinaldo doesn't allow it. He gives her a polite growl and Willow takes the hint!
