Hi there and thank you for using pet coach to address your question. If you have not yet tried the Feliway products, I would recommend doing so. You can find Feliway online quite easily or at your local pet store. There is a spray and diffuser that I would recommend trying. I would also make sure that both cats have their own areas to get away from each other. The problem is, cats are very territorial and many times, having multiple cats does not work out. I hope the Feliway works for you. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

    Do you have the Feliway Multicat diffusers? If not, I suggest getting those. It is a different phermone than the regular diffusers. Also, make sure you have the proper number of diffusers per square foot of house otherwise it is not likely to work. ( https://www.feliway.com/us/Why-Use-Feliway/how-to-stop-cats-fighting ) Also doing some environmental enrichment for them is recommended. They may be bored and taking it out on each other. ( https://moderncat.com/articles/how-enrich-your-cats-home-environment/ ) If all else fails, you can talk to your vet about prescribing behavior modification medications.

What else can I do to get my resident cat to get along with my new cat. It's been over 3 months & there're still standoffs w/hissing, growling & chasing. My new one pursues the resident cat relentlessly. Both are females, 3 yrs & fixed. They both hav
I'm sorry to hear that you're having so much trouble! Some cats, just like some people, may simply have incompatible personalities and may never make good housemates. It sounds like you have done everything right so far and given them plenty of time to adjust, so this is definitely a challenging case! Because of this, I would really recommend making an appointment with a veterinary behaviorist if you're committed to keeping both cats. He/she can evaluate both cats in person to help determine why they're having so much trouble getting along, and will put together a detailed plan for you to address the problem - this may include management recommendations to ensure that both cats are comfortable, training exercises you can do with them that may help, or even medication for one or both cats if necessary.

Kosmo is my oldest female cat & all my 6 cats prefixed,she fight all them,we have had 2 for year now &she still won't except them,what can I do,?
You may ned to just keep them separated. If it has been 2 years, there is a chance she will never get along with them. You could try some Feliway spray and see if that helps or talk to your vet about trying an anti-anxiety drug, like Prozac or Trazodone. http://www.feliway.com/us/#redirected

Hi there and thank you for using Boop by Petco! 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.

Alyssa has always been very affectionate with humans. When we got a puppy she would hiss and growl at him but eventually she got okay with him and now he can sit there licking her and she doesn’t care. But anytime she’s around the two kittens she wil
Thanks for using PetCaoch! It’s not uncommon to hear about behavior like Alyssa. It can take a lot of time and patience for them to get along but here are some tips for decreasing stress for Alyssa in the short term. -Feliway- calming cat pheromone- comes in many forms from pet stores or online. - Adding a litter box. Studies show that the ideal number of litter boxes for a home is #of cats +1 . This is regardless of how clean you keep his current litter box. - making sure she has plenty of “high space”. The safest (and therefore least anxiety-inducing) place for a cat is up. If you don’t already, get a cat tree or put up a shelf or two that she can go perch on. Feeding them in separate rooms with two or three water bowls throughout the home is also a good idea as perceived competition for resources is a common problem in cats. Best of luck to you and your kitties!

We adopted two kitten sisters two years ago, who were rescued from an alley. They have always been friendly towards each other. We moved this weekend and they were traumatized. One suddenly started acting fearful of the other- screeching and hissing
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/

I adopted a cat 3 months ago, he is 3 years old, I already have a cat since he was born, he is almost 3 years old, since the new cat arrived to my house I tried everything I know, everything I read, any advice, etc etc but ... They can't be together
My guess is that you did not do a gradual introduction with them?? If not, you may have to go back and revert to doing that along with these other recommendations. ( https://www.americanhumane.org/fact-sheet/introducing-cats-to-cats/ ) I recommend you put some Feliway diffusers (Multicat) in your house and do some environmental enrichment for them. Usually these two things help. ( https://www.feliway.com/us/Products/FELIWAY-MultiCat-Diffuser ) ( https://www.feliway.com/us/Why-Use-Feliway/how-to-stop-cats-fighting ) ( thedrakecenter.com/materials/environmental-enrichment-indoor-cats ) Hope this helps. If you have more questions you can always opt for a private consultation where we can chat back and forth. That way you can ask as many questions as you'd like. Best wishes.

I'm sorry to hear your cat isn't doing well in your home anymore. If you have enough space in your home, you could try separating the two cats temporarily with a gate while we try to re-introduce them again. Feliway Friends is a cat pheromone spray which can help cats get along better. I see you live in Poland, perhaps you can try your local vet or purchasing it online. You can have them eat side by side, but with a gate between them. That may help them get used to each other's scents and start to associate their interactions with something positive (eating). Make sure that you have separate food and water dishes for the two cats, and at least 3 litter boxes in the house. Take it very slow and don't be too rushed to introduce them again. As much as we try, two cats may never get along but we can at least try to have them be civil toward each other! Best of luck!

I have 2 cats -- brothers -- 4 years old. They hang out together all the time, and "roughhouse" with each other regularly, which I take to be normal. But sometimes, usually at night, they will wake us up with vicious, screaming fights, leaving clumps
It sounds like you have a behavioral issue in the house. One of the cats is trying to be dominate over the other. I would make sure you have 1 more litter box than cat. Also have multiple areas to place food and water. This will eliminate competition over those things. I would try feliway in the rooms the cats spend the most time. This is a pheromone to help with stress. Increase exercise as best you can. They do make toys you can hid treats an the cat has to get them out. Also hid toys around the house at night so Mo and Francis have something to do. IF that does not work it is always best to have a good exam by a vet to make sure the aggression is not due to illness or pain. thanks for using pet coach

I have two cats 2 any 3 yrs old and a few months ago they had a fight full on we separated them and started agin and they were fine but they had another fight for no reason I don't know what to do
How frustrating! Cats can be very hard to "read'. There is almost certainly a reason for the fighting, but it can be very hard for us humans to notice what the reason was because we don't speak Cat. I recommend separating them again, give them a break apart for at least a week, and then restarting the introduction much slower this time. If you introduced them over a week before, do it over 3-4 weeks this time. If you took a month to introduce them last time, take 3 months now. Some cats need a LOT of time to warm up. When you are introducing them, only let them interact or be in the same room if they are both completely relaxed. Often feeding both cats, on separate sides of the room is a good way to start this process. If you try again, and they still fight, I recommend getting in touch with a veterinary behaviorist right away. The more they "practice" fighting, the harder it will be to ever get them to stop. Some cats even need to be on medications in order to get along.
