How to use pheromones, sprays, & treats to help cats get along?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach! I would recommend using the Feliway spray as well and spray the areas where the cats are the most and where they sleep. You can also use a product called NaturVet Quiet Moments calm treats plus melatonin for cats and see if this helps. If you are not having any success and they are still aggressive towards one another, I would recommend discussing this further with your veterinarian as anti-anxiety medications may be the next step. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

I would try a Feliway spray, diffuser or collar. It is a pheromone that helps with relaxation and anxiety. There are also supplements for anxiety. Set up separate areas for feeding and two litter boxes so they each have their own space with an area that they both have access to. Usually over time they will adjust if left alone. If she’s still aggressive there are prescription medications to give her for a little while to help her adjust so please discuss this with your veterinarian.

Unfortunately it's going to take time. That said, there are a few things you can make sure of to help reduce stress, especially in a four-cat household (which is a lot!). Making sure each cat has their own space where they can eat, drink, play, observe, etc without the other cats bothering them can help reduce territorial disputes over these items. Pheromone collars and plug-ins (Feliway) can also be placed on stressed out individuals, or in shared rooms (since everyone seems to be stressed) to help reduce inter-cat aggression. Making sure to have at least one litter box per cat will also help reduce stress and competition over them, and reduce the chances of accidents elsewhere. Otherwise, continued slow introduction of the cats is best. If anyone starts to get agitated or too excited, removing them to let everyone calm down and settle back in is best. Continued aggression and upset may also need a trainer or veterinary behaviorist's help. That said, if your home is very small, four cats may just be too much for everyone to get comfortable.

The make feliway sprays and diffusers you can plug and spray on things to help that she will not be able to get to. If he is smart enough to walk away and not fight then I think they will be fine to figure it out on their own.

The best thing you can do is make sure that each cat has their own private space. You may keep each cat confined to their own room with food, water, and litter box for the first couple of weeks. Once they are used to the new home, you can let one cat out so that they can start to smell each other through the door. After a couple of weeks, you can do supervised time together.

You are doing perfectly! The pheromone diffusers work great but it will take a few days to regulate. Be sure you have enough diffusers to treat the appropriate square footage of the house. I can't think of anything else to do other than getting the pheromone spray and not spraying it on the cats but just put some on a cloth and wipe a little on them each. That may help speed things along. You did great - hope they will start to get along again soon! Cats are funny creatures!

Moving can be very stressful on any species. Cats will sometimes display signs of mis-directed aggression when they are stressed. I would recommend getting Feliway pheromones started asap. These come as plug in diffusers or even collars if the cats will tolerate them. They release calming hormones into the air that people won't smell, but do help relax agitate pets. Give the cats a safe place to retreat to - a room or hideout where they can get away from each other, the dog and people. If possible try to have items from their last home there (a bed or toys). Try to feed the same food, switching it over gradually. I would recommend having several litter boxes in different areas of the house while they are acclimating. If the fights are serious enough you may need to separate the cats into separate areas of the house and gradually reintroduce them to each other. If the behaviours continue or worsen, I would recommend consulting with their veterinarian. There are medications that can help in conjunction with training to decrease behavior problems.
