Unfortunately CL has a lot of scumbags who'd unload sick bunnies just to get them out of the way. So yeah...I'd stick with a safer source.
I have no idea how you got attack rabbits but I know any rabbitry wouldn't sell one without warnings labeled all over the rabbit. Since the interwebs has gone booming rabbitries now have websites to upload available rabbits and litters pages. I really like reading the personality of the rabbits and what they look like before I pay for it or pick it up. Doesn't waste my time and money.
THE BEST website for rabbits is
Rabbit.Org.
It's really a huge guide including breeders, diseases, common solutions for problems people normally take rabbits to vets for, in depth behavior guides, foods, toxic items to rabbits and just about everything. They also have an attack rabbit section. ;D
Sorry to the mods, im spamming up this thread.
