If they eat roughly the same amount, it could be genetic.
Just like in humans, animals can be pre-disposed to obesity, and I actually know of a gene in mice and other rodents that can directly cause obesity.
Yes, it is strange but true, gerbils will eat other gerbils.
Gerbils can (and should) live with a gerbil friend or two of the same sex--that's it. No other animal is safe to live with a gerbil in the same cage or tank.
Put it with a male gerbil and have no other gerbils except them two they will become friends and may have interest in the other gerbil. Hope this info helped!!!!
For their bedding... cat litter or sand.
It is most likely to be Meriones unguiculatus, the Mongolian Gerbil. No other gerbil breed is commonly kept as pets, near to 100% of pet gerbils will be the Mongolian.
I would say there is a small chance two female gerbils could get each other pregnant.
Some times. Gerbils are group animals. They do not lead solitary lives. You see gerbils groom each other and keep each other company. If you only had one gerbil then it would probably live a short life.
No, rats are predatory towards other small rodents. It would kill a gerbil.
The other one has visible bite marks and they bleed. Gerbils can't punch.
Gerbils may start to shed when the weather gets warmer. Other that that, gerbils should not loose hair unless they are sick. If a gerbil is loosing hair, it could be very sick.
Gerbils eat gerbil food that you can get in pet stores. They can also eat gerbil treats,sunflower seeds,pumkin seeds and even gerbil biscuits that you can also get in a pet store.
If your rabbit is very tame, it's about the same but usually rabbits aren't as tame as gerbils So, most of the time a gerbil is more playful with humans and other gerbils.
