It is likely your gerbil died of natural causes and the other one was just disposing of its body. It is not very nice to think on but makes a lot of sense in the wild as a dead body would just attract predators.
No! They will be scared of each other and the parrot might try to eat the gerbil.
Yes, it is strange but true, gerbils will eat other gerbils.
Gerbil food.
Yes they will
It is called DOG FOOD. It is not gerbil food. Gerbil`s usually eat grass, and other small veggies. If you want, or think, your gerbil should be eating dog food please, see a doctor.
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.
I have experienced the death of one sister gerbil in the case of two sister's/cage mates. Believe it or not the living gerbil will actually burie the other and continue on living as if she's not there. Unless the gerbils are starving they wont eat the dead cage mate.
feed it. But seriously, if the gerbil refuses to eat, perhaps try different gerbil-firendly foods. And if all else fails, see a vet. If the gerbil will not eat, you may want to see a veterinarian. The gerbil might have a tooth that is bothering him.
No
with a side of gerbil
Yes. Because when one in nature dies it attracts pradators.So they eat the dead one so the predators dont eat them all. When a gerbil dies just take it out of the cage and bury it or throw the gerbil away in a bag.
If it is stale then yes.
