Looks cute but not a big proponent of providing a cute insensibly wild animal and turning them into pets. Aggression, instinctive reaction or even a playful 'swat' and that 'cute' cat would loose it's cuteness.
If you would look at the story of the puma in their other videos you'd know it has health issues and can't be returned to the wild or it would perish, so being cared for by that couple is best for it.
I think I saw it mentioned somewhere (yeah, I was up all night watching him too) that due to his condition he's between 1/3 and 1/2 the normal size for the breed, and early on had some joint issues to contend with. He certainly appears to be very gentle and docile, and for sure has found a loving home. There are other videos of him cuddled up to Sasha as he reads (or, more precisely,
tries to read - Messi keeps trying to lie across him and head butting him in the face looking for attention). I'd love a chance to interact with him and hear his purr firsthand - he's a beautiful animal! I wouldn't want him climbing onto my bench or equipment shelves, though...

Edit to add - or have him offer comfort while stuck in bed with a bad cold (as I presently am)
