من ساعة ما اتبنينا القطة، هي بتنام في الاوضة.

من ساعة ما is an Egyptian Arabic expression meaning since or ever since. Literally, it is something like from the time that.

So:

من ساعة ما اتبنينا القطة
= since we adopted the cat

Even though ساعة literally means hour, in this expression it really means time/moment, not a literal 60-minute hour.

اتبنينا means we adopted.

It is the past tense, first person plural form of the verb اتبنّى / يتبنّى, meaning to adopt.

So the breakdown is roughly:

• اتبنينا = we adopted
• القطة = the cat

A learner may also see a spelling closer to Standard Arabic, like تبنّينا, but in Egyptian Arabic اتبنينا / اتبنّينا is very natural.

Because القطة is functioning as the direct object of the verb.

In other words:

• we = the people doing the action
• the cat = the thing being adopted

So اتبنينا القطة can only be understood here as we adopted the cat.

If the meaning were we were adopted, the structure would be different and you would not normally have القطة sitting there as a direct object in this way.

Yes, the verb already tells you the subject is she/it because بتنام is feminine singular. So هي is not strictly necessary for basic grammar.

Arabic often includes the pronoun anyway for one of these reasons:

• to make the subject extra clear
• to add a slight sense of emphasis
• to mark a topic shift, like as for her, she sleeps...

So both of these are possible:

• هي بتنام في الأوضة
• بتنام في الأوضة

The version with هي sounds a bit more explicit.

Because the sentence is describing an ongoing situation that started in the past and continues now.

بتنام is the Egyptian present/habitual form, and the بـ marks that everyday present meaning:

• بتنام = she sleeps / she is sleeping / she tends to sleep

After since, English often uses the present perfect or a similar structure, but Egyptian Arabic usually just uses the normal present here if the situation still continues.

So the idea is:

Since we adopted the cat, she sleeps in the room.
More natural English: Ever since we adopted the cat, she’s been sleeping in the room.

Because القطة is feminine.

In Arabic, nouns have grammatical gender, and the pronoun and verb agree with that gender. So:

• هي = she
• بتنام = she sleeps

If you used a masculine noun, you would use masculine agreement instead.

Also, قطة often refers to a female cat specifically, though in everyday speech people may use it more generally for cat.

الاوضة means the room.

This is a very common Egyptian Arabic word. In Standard Arabic, the more common word would be الغرفة.

A few useful points:

• أوضة / اوضة = room
• الأوضة / الاوضة = the room
• في الأوضة = in the room

In informal writing, people often skip hamzas, so الاوضة is a very normal spelling even though you may also see الأوضة.

Yes. Arabic can move parts of the sentence around depending on what you want to highlight.

The given sentence starts with the time expression:

من ساعة ما اتبنينا القطة، هي بتنام في الاوضة.

That puts focus on since we adopted the cat.

You could also say:

هي بتنام في الاوضة من ساعة ما اتبنينا القطة.

That is also understandable, but the original version sounds more natural if you want to foreground the time relationship.

As for the comma: it is helpful, but not grammatically essential in casual writing.

A simple pronunciation guide would be:

men saʿat ma itbannēna l-ʔoṭṭa, heyya bitnām fil-ʔōḍa

Very roughly, word by word:

• من = men
• ساعة ما = saʿat ma
• اتبنينا = it-bannēna
• القطة = el-ʔoṭṭa
• هي = heyya
• بتنام = bitnām
• في الاوضة = fil-ʔōḍa

The exact vowels can vary a little depending on speaker and transcription style, but this will get you close.
