HELP EMERGENCY - My Weather Loach Jumped out of Tank for the night!!!?

I am in a complete panic here. My 3" long weather loach somehow managed to jump out of his tank last night after I went to sleep. I found him on the floor behind the bookshelf that the tank is on. He was still a live but barely and covered in cat hair. I put him back in the tank and he is struggling. He is floating upside down sometimes but then swimming around the tank quickly. I had to handle him in the tank to remove all the cat hair. He keeps moving around and then stopping and looking like he is dead. Anyone have any ideas of what to do? He is in the tank with two goldfish that do not seem to care either way about him. PLEASE HELP ME OUT HERE. I love this little guy and do not want to lose him.
