iso mini female puppy

I'm looking for a female miniature / teacup kind of puppy / dog of about seven or eight weeks old that might need rehoming.
I have a young cat that seems to be very lonely after his brother was just adopted, and feel a really small dog for him should be okay.
he's never been around dogs at all, and will probably be too scared of a larger one, but no more cats please.
contact with details
