Finding the single non viable offspring of Abby and Ziva afffected me deeply for at least a week, in large I think because. It was a complete surprise. The associated smell of unfertilized eggs hits me *hard* every time Abby passes more jellies.
Weird how the mind works, eh?
Id say breed her and plan on pet-homes for all offspring. Poor eyesight isn't much of a problem for pets as others have said.
