My Cloud (zochor) and Fluffy (nekeva) are both intact. However, there always is and always will be a market for polar bear cubs, so I do not have to worry about abandoned offspring.
Actually, I kept pure-bred Siamese for that reason – I had no desire to make even a penny on selling highly desirable kittens, so I knew I would always be able to place them. For some strange reason, my female had only one viable litter, so it hardly mattered.
