My cat us dying. Need positive books to feel better.

My cat has liver disease and has stopped eating. She doesn’t have much time and every day feels like a nuclear bomb has detonated in my heart.

Please recommend me some insightful, light hearted, uplifting, positive and/or funny books that will help me endure. They don’t have to be related to cats or death or grief.

I’m open to any genres except for self help

Thank you!
