I don't know who Fred is. Whenever I see that name, I think of my old cat growing up named Freddie. He was a white cat with no fear. And spoiled rotten too, if you asked me.
Thankfully, Freddie never needed diapers, but I'm sure that if I cut a tail hole in these, they might work just fine. But Freddie was a cool cat, and cool cats don't wear diapers, right?
