When they look fatter then usual?
Your hamster starts making a nest. They also get fatter.
None...
A female hamster can get pregnant if it mates with a male hamster.
They get really round and they look fat.
if the mom makes a nest
There is no specific weight for a pregnant hampster. The only way to know is if the hampster is gaining weight and acting strangely.
A pregnant hamster, by definition, must be female.
No, a hamster needs a mate to become pregnant.
by seaing that it has a big red ball under its stumuk and i have a proble with my own hamster it is pregnant
A pregnant hamster will start hoarding lots of food and will get a little bit aggressive. They start showing the baby bump about a week before giving birth.
You can know that your hamster is pregnant when It's tummy is big and that she bites or makes a sound when you touch her tummy. I know that because my hamster ChowChow had a baby. You know when its coming out when she breaths fast.(when it comes out do not touch it or make a big sound or...It will eat her babies!) Im not telling a lie. And don't look at it.
its slower that than it usually is and its alot fatter
If your hamster is noticably bigger, it is probably pregnant.
