The cougar/puma/mountian lion and the house cat belong to the subfamily Felinae.
The first group roars. The second group screams.
Wrong!
The jag and the puma are the same cat.
You’re thinking of the lynx and bobcats, which are the same as house cats, as in they have purring cords, and meow rather roar.
The puma can be black, tan, or spotted, just like the Jag and the leopard, and are approximately the same size/weight,except that the puma in northern reaches get about 25% larger than the Jag, and apparently live longer.
