Is There A Type Of Cat Called "Boxer?"

Factual Questions
1

I was listening to the old time radio show “The Bickersons” and Blanche was describing her cat and called it a “boxer.” John says “Blanche a boxer is a dog.” Blanche says “That’s how much you know it’s also a type of cat.”

Is this true? I couldn’t find anything on Google. I was wondering perhaps since “The Bickersons” was from the 1940s that maybe it was a nickname for a breed of cat or the name got changed since then

There is no boxer breed of cat that I’m aware of, but kitties can exhibit fistic behavior when messed with.
