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.
Yes, you bleed when you have your period. Menstruation is the shedding of the uterine lining, which includes uterine tissue and blood.
It varies from woman to woman. I think with a normal period you bleed about 7Tbs.
Both is true; while on your period you bleed until a certain amount of blood leaves your system. The number of days that you have your period is different for every person.
it means you are a squirrel :)
They will have a period and bleed like a human female. Doggy diapers are suggested. So is getting her spayed.
Light red period blood is a sign of a period. Spotting may be a sign of an implantation bleed if very minor.
For both genders, it could be an an-al fissure or haemarhoids(piles). For a female it could also be menstrual period bleed.

No. Horses, specifically mares, go into what is called estrus, which is a reproductive stage in which they are receptive to getting bred to a stallion. They do not bleed out nor shed the uterine lining like a female human does. They may bleed a little bit after estrus, but not so substantially nor noticeably like with women or female dogs.

Gerbils noses don't bleed. Many people make that mistake and take them to the vet for no reason. What looks like blood is actually their mucus. They basically have a runny nose and if he has cagemates then I'm not surprised that both of them have it. Hope this helps!
If it is a female it might be having its period.
