thinks there are some magical

我覺得是寫漏了，全句該為：
I think there are some things magical about him.
或 I think there's something magical about him

意為“我覺得他有某些東西讓人覺得他很夢幻/神奇/不可思議/迷人”。而這裡的“某些東西”不是指一些實質的個人財產，而是指他的性格、樣子等。

"I think the thing that's magical about him is how cares for homeless animals". 我覺得他對流浪小動物們的關愛是他讓人感到迷人的地方。

感謝Mee的指正，以上例句的確是打漏了一個"he"字，以下補上：

I think the thing that's magical about him is how he cares for homeless animals.

Two informal explanations:-
I think there are something magical about him=an adj.=having or using special powers to make impossible things happen or seem to happen by a magic spell/charm/potion/trick.
An informal speaking is having a special quality that makes something seem wonderful.eg He has a magic touch with the loving girls and they do everything he asks.
Another informal speaking is, He is very good and enjoyable at love affairs as if by magic

I think nobodyfantasy's answer is good.

a typo/ missing word in ( ) : how ( he ) cares for homeless animals
