I came across [this video](https://www.japaneseammo.com/the-ultimate-guide-
to-%E3%81%AF-vs-%E3%81%8C-the-only-lesson-you-need/) on the difference that I
found particularly helpful, but there was a special case not addressed in the
video that I was curious about. I will summarize the video here as I
understand it, as it is quite long and my question will not make sense if I
don't. (I also understand that this is an incredibly complex topic -- no pun
intended -- but you always have to start somewhere.)

In the first and most common type of sentence, there is a single subject,
which may be marked with either particle. は is preferred, except in the
following situations:

  1. When the subject is new information, e.g. 「ジョンは学生です」 (Roughly, "John is a student") vs. 「ジョンが学生です」 (Roughly, "The student is John"). This use is required with certain kinds of phrases, for example 誰 -- so「誰が寿司を買いましたか？」means "Who bought the sushi?", and this cannot be phrased as 「*誰は寿司を買いましたか？」.
  2. When the whole sentence is new information. Thus「田中さんは子犬を買いましたよ」just states that Tanaka bought a puppy in a factual sense, while「田中さんが子犬を買いましたよ」presents the sentence as being "news" is some way.
  3. When the subject is inanimate (this only applies to action verbs). So you would have「雨が降っている」but not (as far as I understand) 「*雨は降っている」.

In the second type of sentence, there is both a は phrase and a が phrase, which
I will call the "subject" and "object" -- in quotes -- respectively (I
understand that they are not actually a subject and object in Japanese, but
they usually translate as such into English and I don't know any other name
for them). For instance, we have

  * ジョンさんは鼻が大きい ("John has a big nose")
  * 田中さんは犬が好きだ ("Tanaka likes dogs")
  * 直美さんは日本語が話せます ("Naomi can speak Japanese").

In all these cases, the が could be replaced with a は, which would emphasize
that thing as opposed to others e.g.

  * ジョンさんは鼻は大きい ("John has a big nose, but the rest of him is small")
  * 田中さんは犬は好きだ ("Tanaka likes dogs, but not other animals")
  * 直美さんは日本語は話せます ("Naomi can speak Japanese, but not other languages").

Now on to my actual question. I am curious here what happens in the second
type of sentence when the "subject" falls under one of the special rules in
the first type. For example, how would I translate the sentence "Who likes
cats?" -- would it be

  * 誰が猫が好きですか？ (Naively apply the "が for new information" rule)
  * 猫が好きな人誰ですか？ (What Google Translate tells me)
  * 誰が猫が好きな人ですか？ (Modification of previous)

or something else? Similarly, would "The house has large windows" be

  * 家は窓が大きい (Ignoring the "が for inanimates" rule above)
  * 家が窓が大きい (Same as previous but using the "が for inanimates" rule)
  * 家には大きい窓がある (From Google Translate -- edited from original post)
  * 家の窓は大きい (Just one phrase, ignoring the "が for inanimates" rule)
  * 家の窓が大きい (Same as above, with the "が for inanimates" rule)

or something else?

question
particle-は particle-が grammar は-and-が
Conflicting rules for when to use は vs が
> 誰が猫が好きですか

sounds like a direct translation from English. Your second phrasing of this
sounds better, but i would word it more like

> 猫が好きなのはだれですか

I’m not really sure what you’re going for in the second sentence about a house
with large windows. maybe you could clarify a bit more.

But of those sentences 家には窓が大きい isn’t really grammatical.

I think you are trying to take the rules a bit too literally. They’re useful
for initially building simple sentences. But as sentences get more complex and
the nuances get more subtle it’s much more difficult to tease apart, except
retrospectively, what’s going on.

answer
I think the unnaturalness of 誰が猫が好きですか comes not so much from the two が’s as
from the lack of the explanatory-の/ん. In fact, 誰が猫が好き **なん** ですか sounds
natural enough as a question to be asked when both the speaker and the
listener already know someone likes cats and the remaining question is who
that is.

As for the supposed rule, or tendency, for using が with a combination of an
inanimate subject and an action verb, if it is true, we would have to look for
an action verb that can be used for an inanimate subject and also takes what
you would call an “object” followed by が. If any verb satisfies these
conditions, it would most probably be a potential verb. Though I could not
think of a good example, I strongly doubt が would be repeated in a sentence
like that. I would think the subject, regardless of its inanimate nature,
would be topicalized with は, resulting in a similar structure to 直美さん **は**
日本語 **が** 話せます.
