Found it!

 When I stopped at the post box this morning to see if any mail had come while I was away, there is was. Sitting, black side upwards, on my black car seat. Big sigh of relief all round. 

And a few photos.

Milky Way is all alone in the greeting stand alone. Now that his brothers Jupiter and Orion have been adopted he gets lots of attention.

Milky Way

As do the remaining two (the third has been adopted) of Muffin who have settled down in the stand alone in the lobby.

Toast and Hash Brown (don't know who is whom)

Since they have left her condo, and she has come onto heat, she is a reformed character and wants cuddles! (from Tim, I am not brave enough). 

Muffin

We still have Bubbles' kittens Rainbow, Fizz and Suds. And Tiger is the last of his litter since Dash was taken home.
