I am sorry for the loss of your beloved cat. We went through a sad time in much of the same sadness years ago when our 19-year-old cat Simon passed. He had a favorite toy which was a single bell wind chime which he batted around because he liked its sound. We buried Simon in our backyard with his windchime toy as a marker for his final resting place. Whenever the wind blows and we hear the sound of the bell, we think of our family member Simon as still being with us playing with his bell. It brings a smile upon our faces and memories of happy times spent with him. I hope that memories of joyful moments together with your cat will bring comfort to you and Bob. She will live on in your hearts.
