Just so that I am understanding your main concern, you are looking for advice on the inter-cat aggression issues that Smudge is displaying to Jax, is that correct?
Okay. When was the last time Smudge was examined by your vet?
Inter-cat aggression can be difficult to manage. There can be many contributing factors including resource guarding (food, litter boxes, favourite hiding/ sleeping spots), stress/ anxiety, dominance, and other behavioural issues. Ensuring there is equal and ample access to resources amongst the cats will be very important, so that Jax does not have to confront Smudge for essentials/ preferences.
Using a synthetic pheromone called Feliway (available at veterinary clinics and pet stores) can help to quell some stress/ anxiety in multi-cat households.
There are calming foods (prescription, veterinary exclusive) that have been scientifically proven to also reduce some unwanted behaviors.
Sometimes we need to default to medications to reduce stress/ anxiety and reduce aggressive behaviors. Prozac (fluoxetine) is commonly used for this purpose in cats with some success.
I recommend you check out the following website for further guidance on ensuring you are meeting all the environmental needs of all 3 cats to reduce behavioural issues: https://indoorpet.osu.edu/cats
If you are unable to reach a satisfactory level of cat "zen" with the Feliway ( I recommend the plug in version that constantly emits the pheromone for consistent usage), and ensuring their needs are met, then I recommend that both Smudge and Jax be examined by your veterinarian to rule out underlying health conditions, and then discuss starting behavior modifying medications (such as Prozac).
You are welcome. It has been my pleasure helping you today. I hope that the answer that I have provided is satisfactory. Please let me know if you need further clarification. Thank you for using Just Answer and trusting me to answer your question.
