Bringing a new cat home is exciting, but it can be stressful for your resident cat(s). Hissing is a common form of communication during introductions, but how much is normal? This guide explains why cats hiss and offers advice on managing introductions.
Expected Hissing During Cat Introductions:
Hissing is a normal part of feline communication, especially during introductions. It's often a defensive gesture expressing discomfort, fear, or stress. Expect some hissing and even swatting for several weeks as cats adjust to each other.
While hissing itself isn't necessarily aggressive, it's important to watch for accompanying aggressive behaviors like growling, raised fur, tense muscles, and pinned ears. These signs warrant immediate intervention to prevent conflict.
Reasons for Hissing During Introductions:
-
Disrupted Routine: Cats are creatures of habit and dislike changes to their routine. A new cat disrupts their established order, causing anxiety and stress.
-
Feeling Trapped: Rushing introductions can make cats feel trapped and escalate their stress. Always provide escape routes and allow cats to approach each other at their own pace. Never force interactions.
-
Territoriality: Resident cats may hiss because they feel their territory is being invaded. Hissing helps establish or reinforce the social hierarchy. Other territorial behaviors include resource guarding, scratching, urine spraying, and growling.
-
Setting Boundaries: Hissing is a quick and effective way for cats to establish boundaries and assert dominance.
What to Do When Cats Hiss at Each Other:
-
Observe and Wait (Initially): If the hissing is isolated and doesn't escalate, observe the interaction without intervening. If it persists or is accompanied by aggressive behavior, separate the cats to allow them to calm down.
-
Introduce Cats Gradually: Follow a structured introduction process. This typically involves scent swapping, separate feeding areas, and controlled visual introductions before allowing direct contact. The cat exhibiting the most fear should set the pace. This process can take days, weeks, or even months.
-
Reintroduce If Necessary: If introductions were rushed and resulted in constant hissing or fighting, separate the cats and start the introduction process from the beginning.
-
Provide Ample Resources: Ensure each cat has their own resources, including litter boxes (one per cat plus one extra), food and water bowls, toys, scratching posts, and sleeping areas. This minimizes competition and reduces stress.
Final Thoughts:
Some hissing is expected during cat introductions. It's a normal response to a new and stressful situation. Patience and a gradual introduction process are key. Allow your cats to set the pace, provide ample resources, and avoid rushing interactions. This will help them establish a more harmonious relationship.
