How do I get my cat to stop hissing at my new cat?

Jealousy is a normal reaction. Don't yell, scold or punish your current cat for hissing at the newcomer. When he acts nice—or at least nonthreatening—to the new cat, praise him and give treats. If fighting breaks out or either cat is highly stressed, separate them for a few more days.
