One research team was curious about the domestication of felines and their seeming predisposition to this seemingly house pet role, Their research discovered similar to dogs that throughout the decade's felines have been almost selectively bred to be less 'standoffish or confrontational' and more 'sly' animals.
Another research team looked at a broad overview of the overall genetics around felines. From testing feline genetics it was found that there was a correlation between the behavior of the feline and their possibility for domestication, along with that they discovered much data around the behavior and the physical appearance of the feline. a majority of this is speculation and further testing will prove to reveal whether this to be true or not.
