When talking to my toddler, I'd say, 'The cat says 'meow''. I'm not sure if you're using in this context but I hope this helps!I know we can say the cat meows or the cat mews but
Can we say the cat goes "meow" ?
Can we say the cat makes "meow" ?
What is the right verb to use with "meow" ?
I'm afraid "Cat meows." doesn't exist. You can say either "Cats meow", or "A cat meows", or The cat (the "set" of all cats in the world) meows".
PS I'm aware of the difficult time you, as a speaker of a slav language, may be having with the use of articles in English.
