The cats they're my animalCats are my favourite animal.

No "the" as not a specific group of cats. No need for "they" as well as "cats". Adjective before noun in English.

I have two cats and they're beautiful.

I like to films in especially Marvel.

"in special" does not make sense here.

I'm in high school,. I like to reading,I love th and love music and too sleeping.

"reading" not "to reading". "the music" would be a specific music not music in general. You do not need to repeat the "I". "sleeping" sounds better.
