BAD IDEA
If I say meow to a cat, does it understand?
Cats don’t understand your ‘meow’ as words, but they might think you’re a weird, talking cat.
No, cats don’t actually get human 'meows' like a language. They recognize tones and certain sounds, but saying 'meow' at them usually just confuses them or makes them think you’re one of them acting strange. So yes, they ‘perceive’ it, but not in any meaningful way—more like, “What’s this human doing?”
