Cats are very “loving” creatures, and therefore diseases of the reproductive system are not uncommon. As a rule, everything ends with a "banal" endometritis, but pathologies and more serious ones can occur. For example, uterine bleeding, which is quite capable of leading to death.
Why can it start?
There can be a lot of predisposing factors, often their groups are combined, and therefore we will consider only the most common. So, One of the most common causes is injury.
Cats in spring are very serious about procreation, which is why they often fall out of windows, fall under cars, and in other ways get serious damage to internal organs. It is not surprising that the uterus may be among the latter.
Note that there are a lot of large blood vessels in the walls of this organ, which is why any trauma of it is potentially very dangerous and threatens with quick death from massive blood loss. The animal becomes especially vulnerable during pregnancy, as well as immediately after birth. At this time, the walls of the uterus and its mucous membrane swell and thicken greatly, the organ itself becomes tens of times larger, and therefore the likelihood of injury is seriously increased.
Various endometritis and cases of pyometers are very dangerous. With these diseases, pus and other "production waste" severely damages the organ wall, in which, as we recall, there are many blood vessels. It is for this reason that everything postpartum inflammatory diseases need to be treated immediately, without delaying the process.
Other predisposing factors
What else can be identified causes of intrauterine bleeding? Do not forget about the postpartum period - perhaps this is the most dangerous time. Perhaps the birth was difficult, the cat received some kind of trauma, the consequences of which made itself felt. There is a chance that a mummified fetus remained in the uterus, which injured the organ wall. Also, one should not exclude the likelihood of getting into the uterus pathogenic and conditionally pathogenic microflora, which after birth occurs quite often.
There are known cases of uterine bleeding on the background of poisoning by rat poisons. The fact is that over the past 20-30 years, in the production of the latter, compounds have been used that disrupt the blood coagulation process. If the animal eats up with such a "treat", and even gets drunk with water, the development of internal hemorrhage is ensured for it. Blood parasitic diseases can lead to a similar effect, which the animal can easily "pick up" after a tick bite.
Finally, old cats very often (although less often than dogs) suffer from cancer. Uterine bleeding in a cat may well be the result of proliferation or destruction tumors. The neoplasm during the growth period is extremely aggressive towards the surrounding tissues, destroying and "warping" them. Damage to large blood vessels is not ruled out.
The clinical picture of the disease
What symptoms may indicate the development of uterine bleeding? First, you need to pay attention to the behavior of the pet: if it suddenly becomes sluggish, refuses to feed, the skin on the limbs (when palpating) is noticeably cool, and all visible mucous membranes turn pale, you must urgently take her to the veterinarian. All these signs directly indicate inadequate blood supply.
Important! With intrauterine bleeding, the blood comes out extremely rarely: as a rule, all of it remains in the uterine cavity.
Only in very “successful” cases can we notice blood streaks on the root of the tail and the external genital organs of the pet. However, even in such situations it’s not worth panicking right away: perhaps it’s just postpartum discharge, a variant with vaginal injuries is also likely. Show your pet to the vet, he will prescribe the appropriate treatment.
As practice shows, approximately 70% of cases develop bleeding according to the "moderate" principle, and symptoms increase over several days, or even weeks. This is especially true for cancer. The animal’s appetite is gradually lost, the cat is losing weight, she is trying to spend more time, hiding in distant corners. In addition, the pet often sleeps for a long time. If nothing is done, one day she may not wake up ...
So how to stop uterine bleeding? Depends on the severity of the pathology. If a little blood is released, and its presence is due to a mild injury, you can cauterize the gap (in the case when it is located near the cervix). With serious and heavy intrauterine bleeding, the only thing that can save your cat’s life is uterus removal (and ovaries). Of course, if in such a difficult situation it will be possible to deliver the animal to the clinic at all ...
Unfortunately, with oncological diseases, most often the uterus also has to be completely excised. due to the risk of developing metastases. But here it all depends on the stage of the disease and the experience of the veterinarian: it may still be possible to save the organ by cutting out the tumor and stopping the bleeding. But they resort to such a complicated and risky technique only when the pet has breeding, breeding value. If this is not the case, the uterus is best removed immediately.
