they might get pregnant at least once or twice after having babies.
sorry but no you need a girl and a boy gerbil to breed
gerbils are mammals, after they um.... mate.... they have their eggs inside them fertilized. soon the offspring grows in the mothers stomack, and they mother gives birth to it. just like humans
Yes it is possible for brothers and sisters to have babies from 7 weeks old so if you breed them, separate them.
It is very possible that you did not buy two girl gerbils. Rodents are very often misidentified at a pet store. I thought I had two female hamsters a couple years ago but as it turns out, one was actually male. They had babies and we had to take the male back to the store (along with the babies). Be careful; sometimes the males eat their young! Also, pet store often sell pregnant rodents. One of the females could have been pregnant before.
Dreaming that you are pregnant and you have had miscarriages is not a sign or pointer to future troubles, as you can still have babies.
because they body might not be able to produce babies
Gerbils can have a litter about every 5 weeks. Gerbils mate right after the birth of a litter, and the mother can prolong the pregnancy to up to 40 days if she is nursing. A gerbil will produce about 4-5 pups on average per litter, but can have up to 12! With about 10 litters per year with no break, that means about 50 gerbil pups a year! They are rather prolific breeders. :]
no, most gerbils dont bite as often as hampsters only unless they dont have chew toys such as something wooden
frequently.
No you do not need to be pregnant.
Once a month
No, mice often have up to 3-4 babies at one time
It can hurt the development of the baby. Babies to smoking moms are often smaller at birth and develop slower than babies from non-smoking moms.
I think gerbils will more often because they are more curious than hamsters.
Most gerbils enjoy sunflower seeds. I've seen them eaten the most out of a mixture and are often preferred.
