I have two male cats and I made the mistake of bring a female around them. My two males started fighting each other now all my male cats do is fight they won't be around each other and they have to stay in different rooms! They used to love each other before I brung the female into my house! What should I do?

Are the males neutered? If not that's your problem. Males are very territorial when it comes to females, particularly when the females are in heat. Have all of your cats spayed and neutered and the peace will be restored.

Thanks!!
