The new cat keeps hissing at my older one after three weeks, should I be worried or give them more time to adjust?

The new cat I brought home three weeks ago still hisses and acts aggressive towards my older cat. They've had their own spaces and gradual introductions, but things aren't getting better. Should I be worried about this behavior continuing, or do cats usually need more time to adjust to each other?

Answer

It's common for newly introduced cats to exhibit aggressive behaviors, such as hissing, as they adjust to their new environment and furry siblings. Although you've given them separate spaces and gradual introductions, it's important to remember that every cat has its own timeline for social adjustment.

  • Cats may take several weeks or months to fully adjust to new companions.
  • Consistent routines can help ease the transition for both cats.
  • Monitor their interactions for any escalation in aggression.

Your cats might still be navigating their relationship, which can take time due to their unique personalities. Providing each with their own resources like food bowls, litter boxes, and beds can reduce competition and create a more harmonious environment. Positive reinforcement, such as treats and praises when they are calm near each other, may also help them associate the other cat's presence with good things.
