Ooops, no no. They are not real. *blushes* All we do have as real pets are guinea pigs and they are luckily still healthy. I actually thought Jannine might have seen the dragons already on my forum and knew what I've been talking about. Sorry for the confusion.
There's a site called dragcave.net. You can adopt eggs, watch them grow into hatchlings and develope into adult dragons. And if you are real lucky you can breed them. I actually do have a male and female adult dragon, but they can't stand each other, just like in RL.

* Well, and one of the two hatchlings I tried to get to grow up I got for Jana and the girl was real anxious to see her hatchling grow, but well, you know what happened.
If you want, you can take a look here:
