Craigslist states "no animal sales or breeding" but the loophole is rehoming with an adoptionfee. I've been selling rexes, double rexes, beige/blacks/blues, for $10-$15 on Seattle craigslist. I've gota couple multi-gene/color males that breed around 20 girls, and I just keep an add up advertizing different varieties. If I have one of what somebody wants, great, if not, they get fed.
