Scottish wildcats are in danger because of crossbreeding with domestic cats

We still need a good number of the wildcats in order to have enough genetic diversity for restoring their population. I can see by implant the fertilized eggs of wildcats into domestic cats, you can produce more of the wildcats. Probably it is easier if produce them in test tubes. However, I think if the wildcats are born to a domestic cat mother, their natural behavior might change. They will monkey see monkey do by using their mother as example.
