Female rats can have phantom pregnancies. As rats come in to season every 5 days they are likely to at one stage have a phantom pregnancy. Especially if she is living with other girl rats ( who can indeed hump each other) .. So if your rat is building a nest and has not been near a boy, it's most likely to be a phantom!!
Yes.
I have heard of phantom pregnancies lasting as long as seven months!
No. All pet rats are vaccinated.
You can find pet rats in a lot of pet stores, or animal rescues. You can find wild rats just about anywhere.
its not all pet rats its just the ones that are black and white because it looks somewhat like a tuxedo
Yes
No, they can sometimes prevent them!
Pet rats are not vermin. Pet rats are raised in a pet store, laboratory, or adoption center and they are raised to be pets or in the case of labs, experiments. if you are thinking of buying a rat remember not to buy a rat raised as food for snakes. Rats bred to be pets are much gentler and sweeter than rats raised as food.
yes because to have the phantom pregnancy your body secretes pregnancy hormones which is what pregnancy tests look for
for a pet, or for their predators
no
no
