Absolutely. Giving birth and nursing pups takes a ton of energy out of the mother. Combine that with a careless breeding (mother is not fit to be bred - too young, too old, mildly malnourished, sick, etc.) and you have a recipe for disaster.
Back when I was a kid, me and my mom and ex-step-dad had bought two hamsters from a pet store, and when we found out they were a boy and girl she had gotten pregnant and my mom then decided what a brilliant, money making opportunity this was, and so goes the story of how we they unethically bred winter whites..
I'm much older now, and sadly looking back on the situation I'm really upset at the whole thing, especially since my baby (the mother) Candy ended up passing away during birth, and now I know it was because she was simply too old..
Thank you Taxonomist for this, it helped me a lot with coping and understanding. Even though it's been a while, I recently adopted a syrian, and doing so has made me wonder about the past and what could have been done differently, all the things my parents had done wrong, and the most important what not to do now, and even though I still feel really guilty and miss her a lot, I know I was too little to even know what went wrong then.
Okay enough of my life story XD I'll shut up now, long story short, thank you.
