Where are the kittens?

So we've been feeding Miss Marble for almost four weeks now and there's still no sign of her two kittens that had not been rescued.  My sister and I are sharing the feeding schedule.  Miss Marble is living the high life. Eating premium cat food and sunning herself on the deck of my sister's studio. Everytime we feed Miss Marble we ask her, "Where are the kitties?" Or as my sister says, "Miss Marble, show me the kitties!" Miss Marble is keeping Mum.

The little trickster will even throw us off by heading in the direction of one house, then when she thinks we've stopped watching, she'll head in the opposite direction. I have scoured the neighborhood but no kittens!  They would be at the age where they would be tagging along with Mum.  I don't want to think that something bad happened to them.

It remains a mystery.  In the meantime, we will continue to look after Miss Marble.  She's already looking better than when we first met her.  She's trusting us a little more and eventually she will have a home. We might know a few people who would be interested in her. Of course, all prospective parents will have to undergo a rigorous interview process with us. They will need to provide references and meet with our approval.  We take our job as foster moms very seriously!
