This whole post makes me sad and depressed. Your attitude does way more harm than good.
I don't get it, and I don't want this to be taken personally, although I know this is a very, very emotional issue for all of us.
I literally break my back for homeless animals. I do constant outreach and have placed HUNDREDS of cats into their FOREVER homes. I give talks on proper nutrition and healthcare. I do behavior consultations and have saved some human-animal relationships that would have ended in a shelter dump otherwise. I schedule free and low-cost s/n, and I go out and find the people rather than waiting for them to come to me. I stock and donate to and help with our pet-food pantry which ensures that people who have lost their jobs or have ended up on public aid can afford to keep their pets.
How in the world does my belief that bringing cats into a world that has too many cats AND THEN treating them like our playthings, like we are ultimately superior do ANY harm or make any of the above things worth less to the world? I am willing to bet that while you and i would both agree the BYBers and "accidentals" who aren't willing to spay-abort are the crux of the problem...I'm still willing to bet that if you went through JUST the back of Cat Fancy and added up all the litters from all the breeders who advertise there and all the homes those cats occupy, you'd get a BIG number of cats that coudld have been taken off the streets or adopted from a shelter.
Now, I've said it like 5 times, and I'll say it again: I don't for a second doubt th way you, a good breeder or the people on here who have purebred cats love and care for them. I don't agree with some of the things "fanciers" deem right, however. I also don't for a second think those cats' lives are worth less. And I DON'T think it makes you a horrible, heartless person to have chosen to get purebreds. I think it means you made what I BELIEVE is a poor choice. And I'm going to continue to counsel everyone who seeks my counsel to adopt and rescue.
