Grieving a Lost Cat

I lost one of my childhood cats yesterday. His death was sudden (to me) because I wasn't able to be at home with him and only received the news over text. I feel like a piece of my soul is missing.

Do y'all have any recs for a comfort read? Preferably involving a cat. I usually read sci fi/fantasy and I'm ok with romance subplots/plots. I would also love books like the Catnet series by Naomi Kritzer, where cats aren't necessarily characters themselves but play a big role nonetheless.

TIA!
