Line Breeding      To establish a type by having one or two cats dominant in a pedigree can be advantageous.  It is known that for some unknown reason some lines combine well and produce outstanding stock, yet other lines - often from two well known and outstanding animals - simply do not 'click'  and throw back to produce very ordinary stock. This has to be established by trial and error.  When you discover two compatible lines you can carry on, outcrossing occasionally, then going back hard on to the original lines.  Abandon any breeding that throws poor quality stock: it is too difficult to rectify lines that don't match well.  Usually, when you are compelled to go 'out' to a totally foreign line, the type suffers for a gereration or two.  However, the animals and progency become stronger and healthier and gerneral breeding problems are usually decreased dramatically.  Line Breeding Chart
