Cleaning my room

I've finished cleaning my room just now.
I have one cat, so it was so is hard to remove all of his her hair. ( cat is feminine word)
But I'm comfortable now ^^

The weather is so fine too good so I am going planning to go out from just now.
I wanna buy new clothes as Spring is has come arriving to in Japan!

Cleaning my room

I've finished cleaning my room just now.
I have a cat, so it was so hard to clean up all of his hair.

(English does not have masculine/feminine words. If you have a male cat then "his" is correct.)
But I'm comfortable now ^^

The weather is so fine so I am going to go out from now.
I want to buy new clothes as Spring has come to Japan!

("wanna" is slang, not a proper contraction like "I've" or "isn't" so it is best to only use it in very casual writing like texts to friends.)

Good job!  :)
