One of my Male cats has started to bully one of my female cats.they have grown up together since they were both small and have never had any problems at all until about a month ago. I'm confused because there hasn't been any changes in their enviorment pr health that I can attribute it to. I often see him cornering her and her body language shows me she is having high anxiety about it. I have another female cat who he is perfectly nice to. Why is he bullying the one? How do I stop it?

Have him examined by your veterinarian to diagnose illness or injury. Either are common culprits of a sudden behavioral change. Being an intact male may also be playing a role in the behavior. Consider having him neutered. In the meantime, provide additional food/water bowls, beds, toys and litterboxes to prevent food aggression or resource protection. Consider a pheromone product, such as Feliway Spray or plug in diffusers, to decrease any anxiety or aggression in the home.

I would recommend separating them for 3-5 days and introduce a Feliway diffuser and spray into the environment to see if this helps calm her. As the kitten becomes older, he may be getting more territorial and this may be stressing Blaze. You can also try NaturVet Quiet Moments Calm Chews with Melatonin, which can be found online or at your local pet store. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Separate them for a few days, then gradually reintroduce them. Correct any negative behavior immediately. Consider a pheromone product, such as Feliway spray or plug in diffusers, which may decrease any anxiety or aggression. Provide additional litter boxes, beds, bowls and toys to prevent resource protection.
