The inbreeding % should never get over 10%.
But if you have the genetic material, you don't need to inbreed.
IF you want/need to inbreed, you need to be very experienced, and know the lines of your animals very well...
Some people use the argument "inbreeding will double all the positives". This is correct, but it will do the same with all the negatives, and this means a great risk of lethal deceases!
Leave the inbreeding to professionels like zoos, who know what they are doing, and are doing it to save some species
Not again! First of all, there are too many kittens in the world to be breeding to see if you can get another kitten that has extra toes for an experiement. I am glad to see that you have reconsidered. We welcome you to Paw Talk, but also need to caution you that comments or posts like the one that you made can upset all kinds of people right off the bat. 
I can only speak for myself here, but have seen it in the past, I think that the forum believes in taking care of animals and not reproducing them for experiments or fun and not too many people will answer posts too kindly when these ideas are posted. Again, please do not take this as an "angry" post towards you, just a few words of wisdom from me from what I have seen. We want a "happy" forum here. It's a great place to post and a bunch of friendly people from whom you can get alot of help from. Enjoy! And keep up the good work with the spaying and neutering!
