Will my two male kitten brothers fight if I don't neuter them?

Updated On September 23rd, 2025

Hello! I recently got a cat that was pregnant and gave birth to two male kittens. And Im worried of they will fight with each other if not castrated. Im thinking of castrating them but now Im not that able financially and Im trying to postpone it a bit. Kittens now are 3 months old and mother just got spayed. Can you please inform me a bit about this issue. Both brothers are really close with each other now but will this continue when they'll grow up?

Whether they fight or not is going to depend on a lot of factors including how well they get along, their individual personalities, and if there are cats going into heat near them which could lead to competition. Three months is a bit young to be sexually active so they likely won't fight (if at all) until they are older, and you still have time to get them neutered. Looking to see if there is a low-cost or no-cost clinic in your area that you qualify for may also help with getting them neutered sooner.
