Yes, of course. *I know a cat named Rover, as a matter of fact.

Jim the Gardener once had a cat called Dog

And I think Duke is trying to tell you that is what he would like you
to call him- you have no choice in this matter

Besides you're asking someone whose cats very definitely told them
they would like to be called Redunzel and Sarrasine?
