Thanks for all the input so far. I have thought about the collar - making it out of elastic from my sewing basket and attaching a note to that...I will make sure it is something stretchy that will pull off her if she gets caught.

If the collar is still there after several days, I will know she has no home.

I would take her to the vet first - and I have two cats already in my 2 bdrm condo(one of which is the office), so not sure where I would keep her...

My friend Donna who was over for dinner could keep her in the 'shop' at her place, since she is an outdoor kitty...but doesn't know how her other two cats would like it.

Will start with the collar. Any other advice appreciated.

Thanks!
