Hi, I recently decided to adopt a kitten from a cat rescue organization. They say that about a month ago he fell from his cage and onto his face, and the vet says he has brain damage. He also has a clouded over eye, but they say he always had that problem (I've decided to name him Kumo- japanese for cloud). They also say that he had problems before he fell, but we believe that him falling is what caused his problems. I've heard that mannitol helps cats with brain trauma, but will it help a kitten whose trauma occurred a month ago? I am willing to adopt him no matter what his care requirements will be, I just hope there is a way to make him healthy again so he does not have to live with a brain problem. He does not seem to be in any pain. He doesn't purr or anything though, he just lays there slack when you pick him up. If put down, he just sits and bobs his head a little. He also drools but that may be normal. Any advice is greatly appreciated, thank you!
