Only had two. Our previous one was called Kattegat. Our current one (named by our younger daughter a few years ago) is Nick Newton Jonah Meowington (AKA Nick). Named partly after one of our freelance Supervisors.

My wife was due to take some documents to him at the airport from where he was flying out to a job so we had a photo of him stuck to the fridge so she'd recognise him. Our new mainly black kitten had a little white patch on its chin that looked just like Nick's beard, so YD insisted that we call him after the Supervisor. She added the other names "just to embarrass you when the vet calls out his name in the clinic". Didn't work, the veterinary nurse always just says "Nick please"!
