male cats

Question
Once my 2 male cats are "fixed", how long will it take for the neighborhood Tom to leave them alone? He wants to fight with them whenever they are out. Will the effect be immediate or does it take a few weeks? Thanks!

Answer
Dianne,

It takes about a month for the testerone to completely leave the body. But sometimes there are personality clashes and territorial issues that still causes fights.

When there are no more females in heat, the tom should settle down.
