Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered

Please help. My cats are not getting along. We have had zeke (boy) for just over 12 months and we have had our girl sparkles for 2 years. For some reason they had a huge fight and now zeke hisses at her constantly. They cannot be alone together. I have separated them for now and have alternated rooms tonight. They both howl so loud. She wants to be with him but he is so nasty towards her. Any advice please help i can't live with my house divided like this!

This is so hard for you! I would separate the cats, and slowly reintroduce them to each other. Take the cat who is aggressive, and put Zeke in his own room with his own food, water, and litter box. Keep the door closed, and for a few days, feed them both treats on other side of door so they associate each other's smell with a good experience. Then let the other cat in Zeke's room while he is in a cat carrier. They can smell each other, but not be in contact. If either becomes upset or show signs of aggression, remove the second cat from the room, and try again later. Praise them when they interact appropriately. When they are interacting well with each other through the carrier, you can let Zeke out of his room, and see how he interacts with the other cat. Praise them when they interact appropriately, and separate them with any sign of aggression or upset. I would get a cat tree with lots of shelves to give the cats vertical space to get away from each other. I would keep Zeke in his room when you go out until they are comfortable with each other. I hope this helps.

    Poor Cody! It sounds like he was really upset by the fight with your other cat, and I can get you a method that may help them get along better. I would separate the cats, and slowly reintroduce them to each other. Take the younger cat, and put her in her own room with her own food, water, and litter box. Keep the door closed, and for a few days, feed them both treats on other side of door so they associate each other's smell with a good experience. Then let Cody in the other cat's room while the other cat is in a cat carrier. They can smell each other, but not be in contact. If either becomes upset or show signs of aggression, remove Cody from the room, and try again later. Praise them when they interact appropriately. When they are interacting well with each other through the carrier, you can let the other cat out of her room, and see how she interacts with Cody.

I have 2 Ragdoll cats, one male , one female. 3 years old. Both desexed. Both very active, running around. Mainly indoor cats. My female cat growls and hisses when the male cat comes near her. Been going on for 3 months now. How do i stop it ??
Great question! I can give you a method to help them get along. I would separate the cats, and slowly reintroduce them to each other. Take the cat who is aggressive (Sami), and put her in her own room with her own food, water, and litter box. Keep the door closed, and for a few days, feed them both treats on other side of door so they associate each other's smell with a good experience. Then let Beau in the aggressive cat's room while Sami is in a cat carrier. They can smell each other, but not be in contact. If either becomes upset or show signs of aggression, remove Beau from the room, and try again later. Praise them when they interact appropriately. When they are interacting well with each other through the carrier, you can let Sami out of her room, and see how she interacts with Beau.
