Kings (or Queens) of the Castle

Glanced out of our meeting room window on the first floor and caught sight of this pair of ginger pussycats sunning themselves on a very high and apparently inaccessible wall in the shadow of Lewes Castle. You really need to see the scale of things, so check out this link to tweetphoto:

Puss on High

I've never seen this pair before so don't know their names. I will endeavour to find out.
