Is my older cat aggressive to spayed kitten after surgery normal?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 5 lbs

Hi, we brought home our 8 month old kitten from getting spayed yesterday. Our female cat who is 4 years old is now being very aggressive towards her and we are trying to keep them seperated for now as our kitten heals from surgery. Is this aggression normal and will it go away?

Thank you for submitting your question regarding your cats. This can be common after a trip to the veterinarian. The kitten will be covered in different smells. This can cause stress in the older cat resulting in her to act out in aggression. Keep them separate unless they are fully supervised. They should be fine with each other in a few days. In the meantime, you can try a pheromone diffuser to help calm them. Feliway is a good brand. I hope this information helps!
