If humans are (allegedly) more intelligent than cats, why do we think it's a good idea for cats to learn human language instead of humans learning cat language?

Cats have already created a pidgin language that we think is ‘speaking cat’: cats generally use meowing to communicate with humans, not other cats. I think it is polite to engage with cats using this pidgin wherever possible, supplemented with bits of cat body language and human words to fill linguistic gaps.

Cat owners should clearly take the lead, if we discover intelligent alien life.

Yes! Cats have already shown they're smarter than us by adapting their language to communicate with us. Maybe cat should take the lead....
