That's really beautiful. I agree; writing helps. I did something similar when Henry died. I wrote down all of the things about him that I adored. His "Bubbyisms" as we call them:
How you would play fetch with your mousie
Then how you would put your toys in your food and water dishes
Rolling on the floor for belly rubs, and how soft your belly fur was
How you were my constant shadow and how you gave me comfort through some really tough times in my life
Headbutts with that flat spot on your head. I miss your headbutts
Rubbing your wide lil nose and how you would let me kiss it
Cuddles, cuddles and more cuddles
That thing you did when you kneaded with your back feet and put a blanket in your mouth!
Although it was annoying, how could I hate that you woke me up every night for love? Whether you wanted pets, or just wanted to get closer.
Your polka dots where your whiskers were. Your pink nose and white chin, which you LOVED having rubbed. I always said I was in love with your face
The way you tiptoed when you walked. It was quite the strut
The night you brought me a "present" You were soooo proud of yourself
The way you got so excited for breakfast and dinner. The cute way you would ask for your dinner
How you could spot a box within 10 seconds of being in the house, and be in the box 2 seconds later
You had the softest fur. I could pet you for hours, and often did.
How you wanted to be everywhere we were....you could not stand missing any action
When you would swat at us if we walked away from you too quickly...like you weren't done with the pets!
How I could hide a plastic wrapper deep in my purse and I would catch you chewing on it minutes later. How did you know it was there??
Your mushy face. Everyone loved your cheeks. But no one loved them more than me
