The Cat Fanciers Association of America notes that inbreeding may lead to immune deficiencies, more congenital abnormalities and cats that don’t grow to their potential.
What is wrong inbreeding?

What are the advantages of line breeding?
Line breeding can accomplish several goals: 1) produce a more consistent and uniform offspring; 2) identify breeding populations that have no genetic flaws, or identify existing flaws so they can be eliminated; 3) accentuate and sustain more consistent excellence; 4) develop linebred progeny that will provide a ” …
What happens if a mother and son cat Mate?
Bella: Mother cats and their kittens can and do mate. It certainly increases the risk for birth defects and other problems because kittens created through a mother-child mating can get double copies of bad genes. But plenty of vets have spayed pregnant cats with no problems.

What is the purpose of line breeding in cattle?
Line breeding is highly strategized inbreeding. It is breeding to close relatives in order to lock in desirable traits. Line breeding seeks to convey outstanding genetics from one generation to another while minimizing the transfer of undesirable traits.
