The cat was a ‘happy accident’.
If one were to try and duplicate it, they would first need to ensure that the other half of the breeding stock were friendly.
And bobcats are famous for being unpredictable.
The Russians had a genetic study on foxes going where they actually managed to have tame fox after less than twelve ‘generations’.
Something similar could be done with bobcat to create a stable friendly breeding stock base.
But the enviros in this country would freak out about that.
And the cats would also similarly be targeted for hatred much like you’ve seen happen in this thread towards ‘pit bulls’.
Anyway, I'm glad you enjoyed your half-bobcat. Sounds like something I would enjoy too, but I'm sure some others would hate having a 20-pound-plus feline around, especially one capable of jumping eight feet or more off the ground which makes hissing noises very much like its wildcat dad.
Different strokes for different folks, I guess...
