Help! My cats fight after moving to a smaller apartment. What to do?

I am so sorry to hear about your kitties! I would recommend getting some Feliway multicat diffusers https://www.feliway.com/us/Products/FELIWAY-MultiCat-Diffuser which are a pheremone releasing product that can help these situations. A calming supplement such as Zylkene can also be helpful. Ensure the cats each have places they can hide/get away if needed as well as adequate numbers of litter boxes (one more than the number of cats in your household), water and food available where they can eat/drink without being disturbed by the other cat. If they are still fighting despite this, some training may be needed. You can read this article by a veterinary behaviorist for details on this: https://drsophiayin.com/blog/entry/feuding_felines/

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. The following website has some great information about cat behavior by one of best behavior veterinarians there ever was. You may want to search for articles on aggression and anxiety in cats for some more ideas. https://drsophiayin.com/resources/cat_behavior/

I'm sorry to hear that Mary is having such a difficult time with the addition of your brother's cat. I have a few suggestions for you. One option for decreasing stress is to add a Feliway Diffuser ( https://www.feliway.com ) to your house. This is a calming pheromone that will work for a month. I have also had luck with Rescue Remedy ( http://www.bachflower.com/rescue-remedy-pet/ ) which can be added to the water. You could also consider calming music specifically for cats ( http://throughadogsear.com/tace/through-a-cats-ear-1-music-for-calming/ ). All those options are safe for both cats. If you have tried the above options and Mary is not any calmer, then it may be time to discuss short-term anti-anxiety medication with your veterinarian. Good luck! I hope that was helpful and gives you some ideas. Thanks for using PetCoach.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I’m sorry to hear that TC is having some behavioral issues after the move. It sounds like you have tried lots of changes at home, so it may be time to consult your veterinarian about anti-anxiety medications. These have few side effects, typically including sedation, which may help your cat feel more calm and comfortable at home. I hope this is helpful!

He may be experiencing some stress and anxiety from having another cat in the house. You could try Feliway Spray or a diffuser and see if that helps. You could also try Solliquin and see if that helps. If he is still having issues than your vet could prescribe an anti-anxiety medication, like Prozac. http://www.feliway.com/us/#redirected http://www.solliquin.com/

Poor Master Shake! It sounds like he is really stressed about the change of people in the house, the other cat, and maybe even a new environment if y'all have recently moved in with your fiance'. I would start by ensuring your have multiple litterboxes. I would also putting some feliway diffusers throughout the house. This is a cat pheromone that will sometimes help to calm a cat down and help with inappropriate urination. You may also consider putting her on vetriscience's composure chews. If these don't work, I would talk to your vet about starting him on an anti-anxiety medicine like amitryptilline. I have had great success with this to help calm cats down and help them adjust to stressful situations. I hope this helps!

Unfortunately the new cat is likely causing stress and this is a common feeling reaction to stress. She may not want to go outside as long as that other cat is around. It may be difficult to keep the other cat out of your area unless you want to purchase or build a fence. There are fences available that have curvature to the top that make it difficult for a cat to climb over. There are some things you can do at home that can help to manage her stress. Set aside 30 minutes a day for a vigorous play. Use a pheromone diffuser. There is a special prescription food made by Royal Canin called calm which may help. Use food puzzles. Give environmental enrichment. Lastly, your veterinarian has medications which can help as well. Many cats require a combination of therapies. Best of luck.
