Castration is a short-term, as well as long-term conversion for the cat. In the following, I will go into more detail about the behavior immediately after the operation (the first 48 hours after that), as well as the behavioral changes due to the missing hormones.
What is done with a castration?
The scrotum of a cat is opened with a small incision, the testicles are tied and cut off. A suture is often not necessary, the wound is merely disinfected. The operation does not take long, the cat can be picked up one hour later.
In the cat, ovaries, and in some cases the uterus, are removed. Either one or two small cuts are made, the ovaries are tied and removed. The surgery takes longer than a male castration and has a stronger effect on the cat. Stitching is often done with self-dissolving stitching.
What happens in the body of the animal?
During anesthesia consciousness and pain perception are switched off. In addition, a muscle relaxant is administered to prevent sudden movements, which can often be subconsciously triggered during sleep. The narcotic drug acts on the central nervous system, resulting in a deep sleep that ceases when an antidote is administered or the narcotic is broken down. Analgesics, as analgesics, are already given during the operation and continuously fed into the body of the animal. Especially the hours thereafter require a covering of pain reduction, as much as possible. Analgesics and narcotics act on the central nervous system, for example by blocking receptors or nerve cells that have an inhibitory effect.Even hours after waking up, these substances are still in the system! Therefore, the following behavior is normal after the operation of cats:
· Much sleep
· Coordination weakness
All in all, however, the symptoms should not last longer than 48 hours. Not normal is diarrhea, refusal to feed, fever, apathy (cat is not responsive and does not move), low temperature or a hot red wound (infection!). 48 hours to the absolute upper limit! It is best to go to the doctor no sooner than 24 hours.
Castration removes hormone-producing organs. These hormones, also called sex hormones, induce a certain behavior in cats, such as infestations in cats or heat in the cat. If these messengers are missing, of course, the behavior of the cat changes, as well as their metabolism. That is why many cats gain weight after castration. Especially the male sex hormones increase the energy expenditure, so that after the castration a food change makes sense.
