I'm interested in hearing about people's progress with taming ASFs. I know a lot of people were working with them, and breeding for better temperament, but I haven't heard any follow up about it.

As far as mine, I really haven't had a -lot- of luck breeding the nicest ones to the nicest ones necessarily. I mean, mine don't bite, which is an improvement over some people, but I can't seem to get the jumping bred out of them by those means. I can hold them in my hands, but they have to be picked up by the tail, and I always hold onto their tail while they explore my arms, or while they're sitting in my hand, because they just pop up for no reason sometimes!

HOWEVER...
I have been working with a gene, that produces shortened snouts, and less protruding eyes, and sometimes slightly bent snouts. I have noticed that these animals specifically, are much less likely to jump, ever. Even siblings from the same litter, when one has the shortened snout, and one doesn't, they differ in whether they will jump or not. The few ASFs that I have that I can pick up from the top without tailing, hold comfortably without worry, and even pet and enjoy are ASFs with this gene (or combination of genes) that cause the stubby faces. I'm not sure if this is just a coincidence yet or not, but I'm interested, and I'd really love to be able to hold and pet all of my ASFs without having to tail them!
I'm also not sure if this is actually a problem mentally with these rodents, or if it's more like domesticating dogs, where the animals with more puppy like features were the most domestic, to put it very basically. It's possible that the shortened faces make it harder for them to perceive depth, or something along those lines, I'm really not sure what the exact reasoning is yet.
