Kay you almost made me spit soda all over my keyboard! haaaaaaaa
There is a big difference between things we know for sure (which all comes down to the kitties know more than we do) lol And things we do for luck or because we believe it might help.
The advise part is what we have all learned threw trial and error and from other breeders. Things like Saga's charts, basics of breeding. Things a new person may not know. The things we answer when someone asks us as individuals, "what is the most important thing to know about breeding kitties?"
The tips and tricks are mostly for fun, for a sense that we can make a difference. Which is what breeding is suppose to be about. The fun! Though I am going to pick out a pair of lucky pants and socks for the next round of starters, but I can't stand on my head..I would end up in traction.
