I'm so sorry.
Me too. We adopted him 4 years ago from a lady who was moving out of town, along with a younger Tabby. The one who passed, Spooky, had to be over 20 years old, while the tabby is much younger. The lady was first considering putting him to sleep, but we said no way! And he lived a lot longer than we expected, all while being loved up extra.
We all enjoyed the extra pets we gave out!
