May be hyenas also adapter over million year period to bust open bones. But i wonder why they did not develop a brain like ours!

Brains are only developed if there is an advantage and I guess a brain without fingers, our eyes etc isn't maybe as useful as using the fat for energy.

Yp, brain uses tremendous amount of energy so there's a cost. Use too much of it to build the brain and you starve...use too little and same result since you're outsmarted. Rinse repeat until it's perfected.

Heyenas have 2 extra legs to waste energy on. Not much left in the budget for a big brain.

Rats have a similar brain-to-body mass as humans. Cats are fairly intelligent, are they not?

Evolution doesn't converge for all species to some single point. It was enough that hyenas got adapted to their environment, and their mutations didn't make much difference towards larger brains.
