it is not an evil thing to allow your animals to breed, but you just gotta understand what you are getting into. Lots of us here have allowed their animals to breed. Some with heartbreaking results and some with happy results. Here are a few things to consider:
1. Here at LGRS, we are flooded with colonies from people who let their gliders breed and then decided they couldn't handle it. So it's a big responsibility. If you look into the future 5 or 10 years, are you still committed to keeping them? It's easy to let them breed and unfortunately just as easy to dump them. Are you going to keep them?
2. Hobby and home breeders get the whacky idea they can actually make money in low-volume breeding. You can't. You lose money. So if you think you are going to make money, forget it. The only ones raking in the dough are the evil mill breeders and some over-charging color breeders. Home and hobby breeders usually freak out when they get up to ten or twelve gliders and can't sell them - and then they dump them on a rescue or craigs list. very sad.
3. It's hit and miss. Some gliders if they are new parents will kill their babies. Some gliders will abort them out of the pouch if they are malnourished. Some gliders just don't make it and they get eaten by mom and dad who do that to hide evidence of death to avoid predators (natural instinct). So it can be really stressful and heartbreaking for you and your pets.
4. As others have said, there are a lot of gliders up for adoption in rescues. We alone have about 70 up for adoption this week. We re-homed 5 this past month but they usually come in faster than they go out.
5. If you can't afford to neuter them, which costs between $100 - $200 in most places, then you can't afford general health care for them either. So if they get sick what are you going to do? If you can't afford to neuter them then you can't afford to keep them alive when they get sick. Now times that by 2 or 3 or 4 if you let them breed.
so I guess what I am saying is it's a bigger decision than may be readily apparent on the surface. Not trying to be rude, but please think about all these points. Think about the result and what happens to the animals afterwards. thanks
