I am a cat person too. I had a cat, Mittens. He lived to be 13 years old, and he met every other cat my family had while I was growing up. We had another old cat too, so we knew they would be leaving us soon.
So, my family took in two female kittens, orange tabbies, and they comforted us when Mittens and Max passed.
I say all this to say: if you need to grieve, maybe visit an animal shelter. Praying for you, I know it's not fun to lose a close pet.
