I have only ever had moggies so can't really say much about breeders, although I have nothing against them, and I have seen some beautiful cats on this forum.
I would like to mention my experience with rescue centres. When I was desperate for a cat, and had a lovely experienced home waiting for a rescue pet, the rescue centres didn't want to know I contacted 3 in my area.
They were rude, unhelpful, and i was left with the impression that they would rather keep their cats at the centres than let me have one. I was told that they would be in touch if they had anything suitable, and needless to say they never did. They never met me or visited my home, so all their judgements were made over the phone.
Now I completly understand that they only want them to go to good homes, and I am the first person who would put animal welfare above and beyond the wishes of a perspective owner, but the whole thing really upset me and left me with a dim view of some rescue centres, and their staff.
This story does have a happy ending, as I eventualy rehomed a feral kitten which was born in a friends garage, he was just 5 weeks old when I had him and in areal state. He is now almost 6 and the biggest (not fat just huge) cat I have ever sen!.
