Upon entering a pet store, one thing you will usually notice is that there is rarely a shortage of pets. Mice, gerbils, hamsters, ferrets, and others exist in abundance. However, there is a shortage of good, safe, permanent homes for them. Knowing just this fact alone, unless your intention is to keep all of the offspring you produce for the duration of their lives, it is highly irresponsible to pursue breeding them. As cute as hamsters might be, as much as you want to love them to pieces, the work and expense of having MANY hamsters is not something to take lightly.
Some owners breed hamsters for many misguided reasons.
This may include making money or teaching children the facts of life. These thoughts rarely take into account the awesome responsibility this decision makes. Breeding hamsters is not a wise choice for the owner or for the animal. It's just irresponsible. Unfortunately, sometimes accidents happen.
