Lella is home!!! Thank you to everyone who helped out there!!!
I've been thanking folks that I ran into on my search as much as I can and I completely forgot to post that here, too, sorry.
Two big take-aways I have (1) THANK YOU everyone! and (2) never give up on finding a lost kitty. It can take a while (like 3 weeks in my case) but I hear that folks often give up early, unlike with lost dogs.
Cats can be tricky: mine wasn't more than a stone's throw away, she is so timid and they say that a shy one won't even reply to the kind voice she knows and loves until she's really desperate.
I'm so happy I found her before all this rain too--it was torture enough to think of her lost out there, but wet and cold would be incredibly hard to bear.
Thank you again!!!! Julia
P.S. I've removed all the signs I posted in stores and all I could find in the neighborhoods, if you know of any I forgot, do let me know and I'll track it down...
