My 12-year-old cat just met her new adopted sister and hasn't stopped hissing, is this normal behavior or should I do something?

I recently introduced a new adopted cat to my 12-year-old feline, and ever since the introduction, the older one hasn't stopped hissing. I understand this might be a new and stressful situation for her, but I'm unsure how normal this behavior is. Should I step in to help them get along, or is it best to let them figure it out on their own?

Answer

Introducing a new cat to your older feline can create tension, as older cats often take time to adjust to new companions. Hissing is a common reaction indicating discomfort or territorial behavior.

  • Give them both time and space to adjust.
  • Monitor their interactions closely.
  • Create safe spaces for each cat to retreat to if needed.

When introducing cats, it’s normal for the resident cat to express disapproval or anxiety through hissing. This behavior is a way for the older cat to set boundaries. Allow the cats to observe each other at their own pace, and consider controlled interactions where they are rewarded for calm behavior. It’s important not to force their interaction, as patience and gradual exposure are key to fostering a positive relationship. Offering them their own territories and resources, like litter boxes and feeding areas, can also aid in reducing stress.

Frequently Asked Questions

  • How long will the hissing last?

    The duration varies, but it can take several days to weeks for cats to acclimate. Consistent hissing beyond this may require intervention, such as consulting a vet or animal behaviorist.

  • Should I separate them during meals?

    Yes, feeding them in separate areas can help reduce stress and competition over resources.

  • What if one cat becomes aggressive?

    If aggression escalates, separate the cats and slowly reintroduce them. If aggressive behavior continues, consulting with a vet or professional behaviorist is recommended.
