Why does my older cat keep hissing at the new kitten?

Since we introduced a new kitten into the house a couple of days ago, my older cat has been hissing quite a bit at the newcomer. They haven’t had any physical altercations, but the tension is clearly there. Is this an expected behavior for territorial reasons, and is there something I should do to help them get along better?

Answer

Your older cat's hissing at the new kitten is a common behavior, often seen as territorial adjustment. With time and proper introduction, most cats can learn to coexist peacefully.

  • Hissing is a natural way for cats to express their discomfort or establish boundaries.
  • Gradual introductions help ease the transition and reduce tension.
  • Providing separate resources like food and litter boxes can help minimize stress.

When introducing a new kitten to an older cat, it's normal to experience some resistance. Cats are territorial by nature, and your older cat is likely asserting their space. Begin by keeping them in separate rooms, allowing them to adjust to each other's scent through a closed door. Gradually increase their supervised interactions, and reward calm behavior with treats or play sessions. Patience and consistency are key to helping them form a positive relationship.
