Button Thomas giving Kisses

I have just upgraded my laptop and have been trying to transfer files from one computer to another. I have come across some wonderful pictures.
This is my wonderful but very grumpy Siamese neuter Button Thomas, giving little Luka Christmas kisses! I recognise all the fallen pine needles after the tree had been attacked by kittens!
Little Luka will be almost 18 months old now...I wonder if he remembers Button's?
