Missing kittens

Hey neighbors! I emailed a few days ago looking for the owner of a cat who had kittens living under our deck. Since then we've concluded that mom is most likely feral. I've made contact with a no-kill cat rescue that was/is going to come out Saturday to TNR mom and bring the kittens in to be fostered. However, we had some work done in our yard on Tuesday and the cats scattered... I've been leaving out food as I was before but I've only seen mom come back to eat. So I'm wondering if she may have moved the kittens elsewhere. We live on the Morningside side of Highland Park, for reference. If anyone's seen four grey/striped kittens hanging about, perhaps you can let me know? and hopefully we can still get them cared for! Thanks! Allison
