I have received the following reply from Rapidshare support, about their cats:
"Hello,
we are sorry that you got a error message when entering a Captchas.
We use Captchas to prevent automatically downloads.
Automatic downloads from Free-User decrease the download speed from our servers significantly.
Therefore we change our captchas from time to time for better safety and to provide the best possible service for our Premium and Free Users.
Our intention is to prevent automatic screen reading software and this can cause sometimes difficulties reading.
We apologize for the inconvenience.
Kindly note that even though there now are more than 4 letters and numbers in one captcha you still only have to type 4 letters and numbers in the box.
Every captcha letter/number is pictured with an animal and you only have to use the 4 letters/numbers with the cats.
The sitting animal is the cat.
The standing animal is the dog.

So... "The sitting animal is the cat.
The standing animal is the dog."
Got it? Good.
