Why does my 15-pound male cat keep attacking our new female cat? It's getting really intense, and I'm worried she might get hurt. What should I do?

Our new female cat seems to be really struggling to settle in because our 15-pound male cat keeps attacking her quite aggressively. It's becoming a daily occurrence, and I'm increasingly worried she might end up getting hurt with the way things are going. Is there something specific I should be doing to help ease the tension and keep her safe?

Answer

Your new female cat is struggling to adjust in her new home due to aggressive behavior from your male cat, putting her at risk of injury.

  • Separate the cats initially and gradually reintroduce them.
  • Provide each cat with their own space, resources, and attention.
  • Monitor interactions and intervene if aggression occurs.

It's normal for cats to take some time to adjust to new living arrangements. Start by allowing your new cat to have her own space where she feels safe, and gradually allow them to interact under supervision. Encourage positive interactions with treats and playtime, ensuring that each cat feels secure and has access to their own resources such as litter boxes, food, and resting areas. It might be helpful to also use pheromone diffusers that can help reduce tension. Consistency, patience, and gradual steps are key in ensuring a peaceful cohabitation.

Frequently Asked Questions

  • What are pheromone diffusers and how do they work?

    Pheromone diffusers emit synthetic versions of the natural pheromones that cats produce, which can help to create a calming environment and reduce stress-related behaviors.

  • Should I keep them permanently separated?

    Temporary separation can be useful, but your goal should be to help them coexist peacefully through gradual and supervised introductions.

  • Are aggressive interactions normal during this period?

    Some degree of tension can be normal as cats establish their territories, but persistent aggression should be addressed with environmental changes and professional guidance if needed.
