Try to crack this CAPTCHA?

I've previously posted about CAPTCHA image verification of hotmail and gmail being cracked, or massively being crack by spammer using human effort and training bots.

Happen to download some stuff from rapidshare, and saw this interesting CAPTCHA which probably require even more sophisticated programming work to break it.

I even need some time to figure out where are the cats and dogs! But well, since all the cat patterns are the same, I guess it won't be too hard for bots to recognize them, which will be faster than human eventually.
