Gerbil food.
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.
Yes they will
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.
with a side of gerbil
No
No! They will be scared of each other and the parrot might try to eat the gerbil.
yes but most woudent
Noooooooo!!!
If it is stale then yes.
what kind of cheese do gerbils eat
Yes, it is possible and likely that the cat would try to catch, kill and maybe eat the gerbil. You should keep the gerbil in a cage that isn't accessible by the cat.
