you should really take it to the vet. i don't think it is a good idea to put the injured gerbil back in the cage though.
Yes they will
A Gerbil or a Hamster.
Because she is scared or excited and wants to tell another gerbil. Or she is calling for a male gerbil to mate with.
you don't need to if you have another gerbil because they clean each other :)
Then you should get another gerbil so it wont be lonely
Not sure why the gerbil would be sad, unless he is alone. Gerbils are highly sociable and need another one to live with.
Until the mom has another litter, or until the baby gerbil can eat solid food.
Yes,in fact they do. Either another gerbil or a person or thing they just do not like. If you have this problem,I suggest you return your gerbil immediantly or get him/her neutered.
I would say there is a small chance two female gerbils could get each other pregnant.
well, you cant make a gerbil go through a tube if he doesnt want to. you have to wait until the gerbil is comfortable with the tube in its presence, then he might explore it, but that could take a while. If you want the gerbil to go inside quicker though.. try putting a treat or two inside the tube, and make sure the gerbil knows they are there. Then the gerbil will go inside if he wants those treats. (just saying, he might wait a bit) once he is inside it once, he will probably go in again!! =D
Gerbils should always have another gerbil living with it, it provides a much more happier home if its got another gerbil to communicate with. They get lonely and can sometimes die out of lonelyness. They like to groom each other and love the company. They help each other all the time and they live in small groups in the wild. Hope this helps :) x
C. transport a gerbil to another cage
