A new pal?

We may have another member of our family.  A friend rescued a female cat from a bad situation but her older male cat doesn't like her.  We scheduled a play date between our cat and Molly today.  So far, Sassy is sleeping in Carl's chair and Molly is hiding under my chair.  The little face time they had involved some hissing, some growling and some screeching but it was relatively mild.  Sassy seems very calm, she was even purring while I rubbed her under the chin.  Of course, Molly's had a rough time so she may be slower to come around.  We'll have to wait and see.  We're headed out to lunch at noon so we'll put Sassy behind the gate and let Molly explore a little bit.  Sassy will have her litter box and her bedroom.  We have another litter box for Molly and we'll only be gone an hour or so.
