The title somewhat resembles: The Cat with Amber Eyes or The Cat with Green Eyes
(In all honesty I’m not sure myself.)
Some of the details I remember from the book are that the cat had multiple brothers and sister that had (if the main cat had amber eyes) green eyes, or (if the main cat had green eyes) amber eyes. I remember the flowy and descriptive language describing how the cat would move from the trees to the ground.
It was (from the small fragments I remember) a book about a cat who felt like an outcast since his eyes didn’t match his siblings. Sorry that wasn’t much.
I don’t remember when it was published, nor by who, but I believe the cover had an illustration of a black cat with either green or amber eyes. (Another detail, I’m also sure the cat was all black).
I remember the book to be like a short novel a second grader can read, with large font; hardcover.
I’m sorry I don’t remember much, but I do hope you can find it with the little information I’ve given you.
Thank you very much,
