So after doing much research and looking at numerous animals across several species a few things comes to mind.
1) All my animals are pets. This means that I take them out and spend time with them almost daily. If I start breeding then the time I have to care for each animal is shortened.
2) Housing quality and cost. The more animals I have, the less room and money I have to put towards making larger, quality enclosures for my animals. I have plans to build much larger more natural enclosures for Rainbow and Monty (housed separately). They need room to exercise and roam about to stay healthy and happy. I want to create more natural enclosures for my Ball pythons and RTB as well. I want to provide a quality of life for them.
3) Need for breeding? With all that is available and being breed, I can find almost anything that I desire morph wise. So many people are already doing it. I don't need to sell them to pay for the ones I already have. What if they don't sell (unintentional collection growth)?
4) Cost of feeding. Can I afford it? Yes but it does go up.
So Here is the question. For those who don't breed, why did you choose not to?
The future is not written and I might one day change my mind.
