Grammar great.
The word ‘juicy’ is usually elongated in Japanese to ジューシー, so I would personally change that.
Also, you don’t always need a pronoun in Japanese - since you’re already on the subject of your cat, you can simply say かわいいよ。 without the 彼女は.
Finally, you had ‘very’ in your translation, so if you want a literal, word-for-word translation, then stick とても or something like that before かわいい.
Hope this helps!
ありがとう！
このような？

波動拳のモーションインプーといわゆるqcf(quarter circle forward)はnumpad記号で言うと236に当たるだ。[edited]
QCF generally known as Hadoukens Motion Input corresponds to 236 in Numpad notation。
[Ok this one was not really easy to use at all. As the sentences in the details section seem to talk about hypothetical comparisons, as in if we say it is this, then it is that, but the example sentences only went into the direction of corresponds to, according to or in. So not really sure if I used 「でいうと」correctly.
Even less so with「[いわゆる]」, as this is something I haven’t learned yet with a very barren explanation.]
Edit: So as I have encountered this grammar point some more it seems to be the case that you modify 「でいうと」 exact meaning with what follows, so I have to use 「に当たる」 to get the “corresponds to” meaning.
お姉さんは僕と同じでビデオゲームが好き、でも僕とちがって日本語勉強することじゃなくて中国語勉強する。(edited)
My older Sister likes Games like me, but unlike me she does not learn japanese, but chinese.
So, regarding leaving things out, as this is a problem for myself as well:
Could I leave out the second 「僕」 and the second 「勉強」?

Hope pinging you is fine with you 
edit: thanks @matt_in_mito for the correction.
するじゃなくて is wrong, because ではなくて and variations are constructs that can’t come directly after verbs.
Today I just did some vocabulary, so I hope it’s okay that I try to make sentences with some of those words, rather than a specific grammar point.
一昨日、「八百屋」や「保険証」や「何か」や「入口」の語彙を勉強しました。
八百屋で熟れた桃の五個と美味い杏を四個買ました。入口のそばにいくつか梅があって、まだ未熟なので、買いませんでした。他の何かの果物を探しながら、保険証を床に落ちましたはずです。
I bought five ripe peaches and four delicious apricots at the greengrocer. Near the entrance, there were some plums, but I did not buy them because they were not ripe yet. While I was looking for some other fruit, I must have dropped my insurance card on the floor.
The second 僕 is unnecessary but I think leaving out 勉強 would be strange.
Also, this should be することじゃなくて
No, actually I’m wrong. Your sister is the subject of the sentence, so you should have the second 僕. If you were the subject of the sentence then it would be unnecessary.
