why animals doesn't get menstruation?

Question

I know we have same (almost) reproduction sistem with animals, we've got menstruation every month, but animals not. why?

Answer 1

Apparently, the difference is that in most animal females are fertile only for a short period every year (“heat” is sometimes mistaken for menstruation, but it is not. It signals that a female has an egg available.), while human females are fertile throughout the whole year.
Also, you (or any other female mammal) get menstruation only if you are discarding an egg. This is very rare in animals, who, generally, get impregnated every time they have an available egg. In fact, researchers that studied more “primitive” human cultures reported that menstruations there are also very rare and for the same reason. Basically, monthly bleeding is the cost that modern women pay for being fertile and not being pregnant all the time.

Answer 2

Animals have the oestrous cycle, of 'heat' where the female at some times undergoes sexual stimulation. At this time, intercourse can happen, and always does if there is a male present. If there were no male present, then there would be menstruation.

Answer 3

I will give you the linc below for more information
Go to animal estrous cycle

Cats and dogs, on the other hand, have an estrous cycle, during which the ovary is primed to produce an egg and the female is specifically receptive to mating. The estrous cycle consists of estrus, the period of mating, preceded by proestrus and followed by metestrus. During the breeding season, one estrus cycle is separated from the next by a brief inactive period known as diestrus. The longer quiescent period during the remainder of the year is called anestrus (literally "no estrus").

Intact female cats, called queens, reach sexual maturity at about seven to nine months. The age of sexual maturity varies with individuals as well as with breed--Persian cats, for example, tend to experience their first estrus much later.

Do Cats Have a Breeding Season?

In most cases, yes! Unlike dogs, for whom estrus occurs approximately every six months, female cats go into heat several times during a single, prolonged breeding season. The breeding season is controlled by the number of hours of daylight (the same is true of horses). In the Northern Hemisphere, the feline breeding season lasts roughly from February to September. Many cats (not all) will stop their estrus cycles (go into anestrus) in the fall and early winter, when there are fewer daylight hours. It is interesting to note, however, that indoor cats may cycle throughout the year because electric lights give them about the same light/dark cycle throughout the four seasons.

Answer 4

Animals also menstruate during mating seasons. Humans mate all throughout the ear.

Answer 5

my dog gets menstruation once every 5 months or something. i'm not sure because it's the first time for me having a female dog.

Answer 6

all female mammals menstruate but all species have different cycles animals go by mating season or when "IN HEAT" and humans monthly
just as we all have different gestation (pregnancy) periods

Answer 7

They don't reproduce the same as we do. They go "into heat". This means they are ready to reproduce and the male will inseminate the female. If the female is not in heat, she will move away from the male when he tries to mount her. It's a different process.

It also makes humans very very special - Biblically speaking, we are set apart from animals and this is one of the biological qualities that make us unique in all the world.

Answer 8

Female dogs do. I would use the correct term for this type of animal, but I'd probably get another violation notice.

Answer 9

It is false. for all mammals, you have menstruation which is the end of a non-fertilized egg

Answer 10

They do. its not exactly the same but they do.
