Handling Aggression Between Cats
If you have dueling cats, don't let them "fight" it out. Chances are they won't stop. A loud clap of your hands or waterspray will interrupt the spat. Provide separate bowls, beds and litter boxes in different areas of your home to avoid confrontation and offer more than one perch, as space is a safe haven for felines. Neutering males also helps, making them more docile.
