Birkenhead has just been to the vet and they told him he needed to start watching his weight. Apparently he has gone from 4.2kg to 4.6kg in just 12 months. Consequently the humans have put him on a diet. In fact he is so embarrassed he wouldn't let me show you a picture, so this is only a visual representation.
Birkenhead blames the fact that he has been locked in cat clink for a month whilst the humans were on holiday. Obviously I continue to maintain my perfect (if somewhat curvaceous) figure.
(p.s. I would provide a links to the producers of these fine images
but can't find the originals so thanks to both.
If you know who you are let me know and I will be happy to do this.)
