I'm making a book

Yes, another. It's about these teenagers (ages 14-18) who where selected to make choices that will affect the world forever. It follows a girl named Chanile (sha•neal), a cat (I know I use cats a lot) who got taken to a laboratory where she was forced to take a test, and then she was taken from her home and given a room to sleep in in the lab. She had to work with a horse (the one I was talking about in an earlier chapter) and others you haven't seen before, like a black sheep, a deer, a rabbit, and a dog. They all are good at different things and use their skills for good. Sorry if this makes literally no sense, I'm not paying attention. Here's what I have as the description and chapter so far
