Will two male kittens fight when they get older?
I have 2 neutered males and one spayed female. They do get into “spats” but they are just playing and it’s not serious. None of my cats are related. They are very happy cats and love each other. It’s important for their health that you get them neutered, (prostate cancer, etc) besides, they won’t want to get outside, won’t spray (pee), etc. Only male cats that aren’t neutered get into fights, etc. Besides, if your kitties were to accidentally get out, they won’t be getting female cats pregnant!! If you are going to allow them to be indoor/outdoor cats, fixing them is a must.
