Rylee is used to going out and coming back home. We live in an apartment and she always does that. She goes out and comes back to cellar and I go down to pick her up. But this time, she was never back. I searched my entire neighborhood and there's no track of her. Her kittens are waiting for her and it breaks my heart.

She has black mark on one of her paw(left leg)
She has white fur on her belly and her face is a mix of white, brown and black.
