I am so glad you got in touch and hope all goes well for hte pick-up. And as you said, they don't know you and may have been wondering why you had dumped these cats on htem!
The babies are home and safe!
I still don't have a good explanation. She said she was working a lot though, so maybe she just forgot about them? I find that unlikely, considering she has pets herself.
At any rate I decided not to make a big thing of it. I have my cats back, and they are just fine. I think Sammy got some exercise from hanging out with her dogs (apparently he loved them. Good news for me when I get a dog a few years down the line!)
All is well. Thank you so much everyone
Expect some new pictures soon, I finally got myself a good camera.
