Breeding a purebred cat requires a selection of partners to concentrate the desired qualities, while limiting inbreeding.
The partners are sometimes geographically distant, with incompatible characteristics (impossible breeding), or the female with a health risk (coryza, etc.).
The abortion protocol is chosen according to the stage of gestation, but also according to the species, race, clinical condition of the female, and the owner’s ability (sensitivity, financial, etc.).
Article de HartThe purpose of this article is not to “demonize” castration, which has clearly demonstrated benefits in different contexts (see articles: castration in males, breast tumours in cats, breast tumours in dogs, uterine pathologies), but to review current scientific knowledge of demonstrated and/or suspected adverse effects of castration in males and females.
Early castration is the surgical removal of gonads (testicles or ovaries) from non-pubescent animals (<4-5 months).
Numerous scientific studies, combined with a decline of more than 20 years in this practice in the United States, show that early castration in cats does not involve more adverse effects than castration at a more traditional age (5 to 8 months).
Nevertheless, this practice remains controversial and confidential in Europe.
The objective of caesarean section is to give birth to live foetuses, without increasing their possible suffering (during dystocia*), with primary reflexes present in breathing, sucking and burrowing.
The terms "synthetic derivatives" or "progesterone analogue" refer to drugs commonly used to control the reproductive cycle of dogs (and cats).
Owners frequently ask if it is possible to medically prevent their dog's coming into heat. They consider this approach to be less harmful (or even "barbaric") than surgery. Therefore, it is necessary to know the indications and limits of all the molecules available for this use.
During diestrus, the physiological increase in plasma progesterone concentration (produced by the corpus luteum) stimulates the production of growth hormone by the hyperplastic ductular epithelium in the breast tissue. The result is transient secondary diabetes mellitus where the sensitivity of target cells to the insulin signal is significantly decreased, resulting in major insulin resistance.
Progesterone and growth hormone disrupt the binding of insulin to its membrane receptors and its regulation (and thus prevent glucose from entering the cells).
Canine herpes virus is an enveloped virus, which can be transmitted by transplacental, venereal (semen, vaginal secretions) and oro-nasal routes.
It is therefore a sexually transmitted disease.
Abortion products (fetuses, fetal envelopes) can also be contaminants.
Acute mastitis is primarily a postpartum accident but can very occasionally be observed during pseudogestation lactation.
