sentimental: My grandmother passed away two weeks in 2005.   She had given me all of her Christmas decorations a few years before that.  Her death made me appreciate that even more than ever

My most treasured item is her ornament that she had for her cat Barney.   That cat was her world.

I had a cat named Barney too! We was a one-eyed grey tabby. What kind of ornament is it?

Its a porcelain one.   Barney was a black cat that lived into his 20s.  I loved that cat

Wow, that's quite a long life for a cat. I'm glad you got to enjoy so many years with Barney.
