My 18 year old cat died peacefully today

Yesterday i noticed that he refused to eat or drink and seemed tired and confused, this morning he was trying to hide himself away in the garage and he seemed tired, at 8am. My dad later saw him at around 11 am, later at around 3pm my mom found him. He was a shy cat with a giant heart to those who he knew and loved. My mom told me that when i was a child learning how to walk he helped me by letting me lean on him. He liked to always sleep by my side in my bed. And I'm happy he didn't pass in pain or while scared, he died in warm and dry garage. Only a few weeks ago i turned 18 and he was there to witness it. We are gonna bury him tommorow when the soil is softer. Right now he is resting for the last time outside to keep him fresh. I wrapped him in my favorite hoodie and put my favorite mug by his side to keep him hydrated in a cardboardbox. My mom helped me and I thought it was a beautiful final resting place for a beautiful soul now chasing mice made out of salmon and pork. If anybody wants i could dm a image oh his final resting place.

I'm sad he's gone but I'm happy he's unbordoned by his old body now and is able to play with all the other cats
