The optimal age for cat neutering is debated, with early neutering offering population welfare benefits while later neutering may support individual development.
Neutering age involves a trade-off between preventing unwanted pregnancy through early neutering and allowing normal pubertal development. Evidence supports that early neutering at 4 months is safe and effective when performed by experienced surgeons. The population welfare benefit of preventing unwanted litters is substantial. Individual cat welfare from early neutering is comparable to later timing in experienced hands.
