How many cats?

This little festive offering amused me...but don't expect me to know the answer to 'how many cats'...each time I count them I come up with a different result!

If you think you have the definitive answer, let me know!


*Update.
As has been pointed out to me in comments it's twelve, as in the twelve days of Christmas! Duh @ me. Hey, I told you my brain is addled recently but I like the picture just the same! :o)
