Well, well, well, do you really need to ask the nations for a name, what's wrong with you there are hundreds to choose from. My dog is named Mabon from the Mabinogi (Welsh myths and legends) Mabon was the bravest of the knights.
I saw a court case on TV where a prosecutor was called Miss FLEAK - that always struck me as a good cat name. I think if I got twin kittens now I might go with Fleak and Finbar!
The whole family got to choose a name for our first cat when I was a child. His full name was Joseph Shenanigan O'Shaunessey McGillicuddy Pryke…..or Joey Puss.
When my daughters were young they named their kittens and cats after Musicals, they had Mack and Mabel, Halfa (Half a Sixpence) and Barnum (Barney for short)
We had a Smokey, a Tia, and a Tinker. Smokey was a stray brought home from the Flying Club. She stank of cigarette smoke (poor thing) so that's how she got her name.
My suggestion is Jasmine already chosen by someone up thread. Shortened to Jazz it could encompass your DHs love of the music. DDs cats are Maisie and Grace
