Intruder.

Spotted through the kitchen window. I had to zoom in quite a bit, so excuse the quality.

Neo was running from room to room trying to get a look at something. At first I thought it was just the birds, then I heard the tinkle of a bell, and saw the cat walking towards the birds.

There were 3 birds, one flew away, but the other two stuck it out. Eventually the cat got bored, re-traced his steps and disappeared. As soon as he went the 3rd bird came back, and they spent the rest of the morning sitting on the fence in the sunshine.

Neo had a lovely time watching all the activity, Sophia slept through it all, on the ironing.
