The second brother’s cat is very loud?
Yes.
Was one of the cat’s deaf?
In particular, the second brother’s cat (i.e. the louder one)?
Were that cats in question Felis x catus, your basic house cat?
Are both cats alive?
The second brother’s cat is at the first brother’s house (i.e., not his home) hence the mewling?
Another one from Futility Closet, Mahaloth? 
Does this occur immediately after the brothers pick up the cats?
I misread that. I might as well ask it. Was one of the cats dead?
(As for deafness, wouldn’t it be more likely the deaf one is quiet? Just asking as a scientific point, not part of the riddle.)
Is one of the brothers deaf?
Yes, or at least hard of hearing.
Yes to both.
No.
Yes, I love their podcast.
No.
Neither cat is deaf, but one is hard of hearing.
Yes.
Nope.
Cats don’t really meow at each other. (A kitten’s mew is really an alert to its mother that its there. Once they separate from the mother, they stop.)
Meowing is a domesticated response to get human attention to fulfill some need of the cat. Cats communicate with each other through mostly body language, scent, and touch. Cats will react to threats with hissing and such, but they only really meow at humans.
It’s considered to be something they instinctually do instead of a learned thing.
So deaf cats meow. And because they can’t hear themselves, they tend to meow loudly.
OK, so this one is over because you guys annihilated it.
The hard-of-hearing cat meows loud to hear itself.
The silent cat does not meow because his owner is deaf and does not speak. Cats do not meow unless they are around owners who speak and they realize they can get our attention that way.
The first brother is deaf and his cat has given up on meowing to get his attention. The second brother is not deaf, but his own cat is hard of hearing and therefore doesn’t realize he is meowing louder than necessary to get the second brother’s attention.
ETA: seconds late! 
Interesting. Thanks.
Lesson: Riddles do not always get love. Politics and ethics may not mix.
I recently attended a gathering. There I asked a group of strangers a question about Virginia state politics. That was OK because they all knew the answer to my question and the question was (mostly) warmly received. But when I later asked the same group an ethical question, one to which I am sure no one knew the answer, I was told to go away and not come back.
How had I offended?
BTW, the above story/LT puzzle is not actually true. It is just a riddle.
Was either of the questions related to abortion?
No
- Is it something specific to Virginia state politics?
- Would the puzzle work if the word “Virginia” was instead, say, “Alaska”?
Do you know the answer to the 2nd question?
If not, does anybody?
