Your story is truly moving. It reminds me of one of my cats, who passed away at the age of 28. Her name was Sanny, and she was three-colored: white, black, and brown. She was the sweetest cat I have ever had. I have missed her since 2010. I don't visit her grave, but she is always in my memory. It's amazing how attached we get to our pets... Have a great day @Taisei Koshida
