I bet that cats and dogs actually have their own language like people do.
And then like, when people meow at their cats and walk off, I bet it's like, the cat says "hello" and you're like "apples!!!" And the cat is like "Excluse me?" And you're like "goats! Maybe!" and the cats like "Do you even speak cat?" and you're like "Pizza umbrella paper!" and the cat gives up and walks away.
But, with dogs, when you throw out random words they're like "Wow!! You know some words in dog?! That's great!! Good job!! Keep trying!"
