The Question
“We’ve had our cat for four years. He’s very sweet and gentle. Our other cat died recently, so we adopted another cat, a female, nearly three years old. They were finally getting along and playing after a rough few days. Then last night she came to the bedroom, and he followed shortly after. I was petting her on the bed, and he jumped on the bed. She ran over to him in an aggressive manner and swatted him on the face, so he left. Then a few hours later the same thing happened. He hid under the bed this time. Is this something that they’ll just have to work out for themselves, or is there anything we can do to keep that from happening again? We don’t like how he’s afraid of her.” – Linda
Quick Info
Dear Linda,
I am sorry for your recent loss, and I understand how important it is for your gentle boy to feel safe as you welcome your new cat into the family. What you are describing is actually quite common in feline introductions. Cats are territorial by nature, and while progress has clearly been made if they were playing together, sudden setbacks can occur when one feels insecure or overstimulated, especially around prized resources like your attention or the bed.
The good news is that with patience and a bit of structure, harmony is very possible. Continue reinforcing positive associations when they are near each other, such as offering treats or play that both can enjoy in the same space without competition. Give each cat predictable individual attention, so neither feels they must “guard” you. If she becomes assertive, avoid scolding, as this can increase tension. Instead, calmly redirect her to another activity or space. Providing vertical options like cat trees or perches can also give them both escape routes and a sense of control, which helps reduce conflict.
This is not something they simply need to “work out” on their own, because fear and repeated negative encounters can harm their bond. With your support, consistency, and by ensuring both cats have safe spaces, you can guide them toward a peaceful relationship. You might want to try using calming aids, such as synthetic feline pheromone diffusers, which can also smooth the transition. Make sure they are the “multi-cat” versions. Over time, with gentle management, their relationship should stabilize, and your sweet boy will regain his confidence. If you need support through this process, please don’t hesitate to reach out to us at Pangovet. We are happy to guide you through their socialization.
Best wishes,
Dr. Paola
