This is actually a bad captcha.
All cat pictures are the same (tail in same position, face the same), the cat is just rotated.
The letters can be easily ocr'ed, thus removed from the screen, leaving only the animals visible, so you can detect which one is a cat or not.
All letters and cats are separated so it's even easier.
Recaptcha is much better than this...
