Some guy rehoming a purebred Egyptian Mau!
Sad. Sounds like the cat was given to them and its not a "dog" cat, so the person is trying to find a good home. He probably doesn't even know which breeder the cat was from unless he has papers/registration.
If he's the original owner of the cat, then it could be that the original breeder no longer is breeding and therefore, won't take back the cat.
Personally its VERY pet quality Mau. I might even question if its a purebred from the picture shown. At least he IS neutered, so he can't breed.
