Feline Recognition Aggression After a Vet Visit

Meet Cleo and Gus Gus

These two are usually the best of friends and love nothing more than cuddling up together. However, after a recent trip to the vets for Gus Gus, Cleo showed signs of feline recognition aggression.

This can happen when one cat smells different after being away from home, such as after a vet visit. When Gus Gus returned home smelling unfamiliar, Cleo unfortunately reacted negatively towards him. Their owner, Jordanna (one of our RVNs), quickly recognised the warning signs, which can include hostile body language, hissing, growling, and lashing out (swiping or biting).

She immediately separated them and began a gradual reintroduction process, which included:

  • Initial separation
  • Scent swapping
  • Feeding near each other
  • Playing near each other with their own toys

All interactions were closely supervised so any tension could be managed early. Positive reinforcement was used throughout, and the cats were never forced to “work it out” themselves. 

Jordanna also used Feliway Friends spray and a plug-in to help introduce calming, friendly pheromones into the environment.

We’re pleased to say that after around 5 days, Cleo and Gus Gus were back to their normal, happy relationship. It’s important to remember that every cat is different, and in some cases this process can take longer — patience really is key 🧡

Tips to help reduce the risk of feline recognition aggression:

  • Bring both cats to the vet at the same time where possible
  • Place familiar blankets or bedding in carriers so they smell like home
  • Leave carriers out all the time so they become a safe, familiar space rather than something only used for vet visits
