All surgery requires a full clinical examination and blood tests are recommended. Your cat will be carefully monitored during the procedure with devices that measure heart rate, breathing, blood pressure and oxygen saturation.
Kittens should be desexed when 4 months old and greater than 1 kg in weight. In females, it is essential (if not breeding) to prevent unwanted pregnancies and mammary cancer. In male cats, this prevents roaming and fighting, which leads to abscesses and the spread of FIV (feline aids).
One of the most important reasons for having your pet de-sexed is to be part of the solution to the pet overpopulation problem.
A single unspayed female cat or dog, her mate and their offspring can reproduce exponentially leading to thousands of unwanted kittens and puppies within just a few years. Many of these animals die from malnutrition and disease, while others are found and rescued by charity groups who quickly become overwhelmed by the large number of animals they receive.
Since many New Zealand households already own pets, supply far exceeds demand and sadly many animals are euthanised due to a lack of available homes. Only de-sexing will reduce the number of unwanted animals.
