clean it make sure there is no blood left
Yes, but they may not sit there looking you in the eye.
Gerbils secrete chemicals called porphyins from a gland by their eye, for various reasons. This is often mistaken for blood. If the amount is excesive and is forming a crust, the gerbil might be stressed. If it is only a small amount, then this is fine and nothing to worry about.
because they are bloodey normal u ugly vegan
No.They can only see to about 3 1/2 feet.
Gerbils do not have periods as they are oestral mammals and not menstrual ones like us. Some oestral mammals have a bloody discharge, but not gerbils. What you saw was most likely to be a smear of porphyrins from a gland near the gerbil's eye.
if your gerbil doesn't open its left eye, something is probably wrong with it because i have 2 gerbils and and their left eyes open
This is completely natural behavior. When a gerbil opens their eyes, they often only open one eye at a time. In a few days the other eye will open.
only the newer MoH games have a little blood if you get a kill up close but very unrealistic.
Other gerbils.
Gerbils are an animal and can not be "invented".
Male gerbils can be neutered, but it is not recomended. Female gerbils should not be spayed. In general male gerbils should not be neutered unless there is a good reason for it.
Pick up the gerbil and push its eye lid up.
