How long does it take for a cat's testosterone levels to decrease after being neutered?

My cat was neutered about a week ago, and I've noticed he still seems very active and is displaying some of the same behaviors as before the surgery. I'm just wondering how long it typically takes for a cat's testosterone levels to decrease after being neutered. Is there a typical timeframe for when I might expect to see changes in his behavior?

Answer

It's normal for your cat to still exhibit some of the same behaviors soon after neutering. It can take some time for testosterone levels to decrease and for behavioral changes to become apparent.

  • Testosterone levels gradually decrease over weeks to months.
  • Behavioral changes are often seen over time as hormone levels taper.
  • Activity levels can remain high post-surgery, which is typical for young cats.

Neutering affects hormone levels, but it doesn’t cause an instant change in behavior. Typically, you might notice a decrease in roaming, aggression, and certain territorial behaviors over a few weeks to a few months. However, every cat is unique, and sometimes their energy levels and playfulness remain high as a part of their natural personality. If behaviors you expected to see reduce do not change over time, it might be good to discuss this further with a veterinarian.
