Selective breeding does mean that you take undesirables out of the gene pool, in this case, turning them into fur to be sold which further funds the experiment.
Maybe in 10 or 20 years when this is further along I would be interested in seeing how a Fox would do as a pet.
The primary goal of showing that this can be done at all, apparently has also been accomplished apparently decades ago. I can't imagine that they're not already in the refinement stage.
10 or 20 years later the risk you take has been dampened because people have had Fox pets for complete life-cycles which means more of the caveats of ownership are known. And the breeding location has had even more time to breed out undesirable behavior.
A win-win of sorts as a consumer. Of course with the caveat being that the place could go out of business because of a lack of buyers.
You did mention that they are Reportedly pretty good pets, do you have a source on that? I would enjoy reading more on the subject.
One issue I have with them is how high pitched and loud they can be, despite being nice otherwise.
