not a bug, more of a feature request for next update: do not breed siblings

[Kayleigh McMillan]

I'm not sure if we would have a happy community left if suddenly back breeding and sibling breeding wasn't possible anymore.
I like to work towards a goal as well and line breeding is very important in this and I do not like to mix genes at all.
Unless I carefully selected two cats with certain features I like to combine in their offsprings, which I frequently do, and the siblings I would love to remain to breed together now and in the future.
These are pixel beings anyway.
I took a dive in a breedable where sibling breeding and back breeding isn't possible and I think they did this to encourage the market but I find myself very frustrated about that.
