Kittens in the petshop! I'm not used to this sighht - cuteness!

Can you just explain what the kitten at the front is doing,,,,,,:ssign2:

Gawd knows, had its back to me. Took me about 8 shots until I got one where they weren't just fuzzy blurs! I can't just walk past this shop, always have to peek in the window and see what the kittens are up to :oD
