In addition, we've also shown to be capable of far more empathy towards others of our own race and others, compared to any other species out there.
The simple truth is that if any other species had the destructive potential that we have, they would simply exterminate themselves without ever questioning their actions. So don't be so damn vindictive of humans when comparing us to animals.
As an aside cats are slightly odd for domestic animals as they're arguably semi-domesticated versus dogs or farm animals. African Wildcats look and act a lot like house cats in videos and are genetically similar, which I think is part of what makes them fun as pets.

What you might not know, is that in old growth oak forests, most trees were accidentally planted by squirrels.
The acorns that they forgot and didn't retrieve, sprouted and grew into oak trees.
So the analogy of a squirrel as ruthless acquisitor is not quite apt, because their manner of caching their hoard actually helps to plant the next generation of trees.
(Acorns do not sprout as well when the just fall to the ground.)
Nobody gets paid just to fuck up the environment. They get paid to increase sales or whatever and the consumers are buying their shit to help them survive in one form or another.
Someone fucking up the environment to garner an extra $100K or two on that annual bonus isn't doing it for survival. Wolves aren't taking down entire herds of deer they'll never eat so that they can say they have more rotting deer meat than the other wolf packs. Domestic house cats are the only animals that I can think of that demonstrate such behavior, with the modifier "domestic" being emphasised; i. e., we made them like us. (Yeah, that last bit is a stretch.)
I'm sure there exist other species that hoard, just because...well, we can't be the only ones. But we're the ones with the mechanized means to do at destructive scale.
