Cats generally begin to mature sexually at six months, with most starting to come into heat at eight months old. Therefore the best time to de-sex is between six and eight months, when de-sexing is the most appropriate time. In principle, it is ideal to perform the operation after the cat has reached physical maturity and has been in heat once. At this stage, the cat’s reproductive and corresponding organs are already mature. Surgery too early can easily cause urinary stones and other reproductive and secret urinary disorders.
