How to help my scared cat who hides from my other aggressive cat?

This is so hard for you! I would separate the cats, and slowly reintroduce them to each other. Take the cat who is aggressive, and put Zeke in his own room with his own food, water, and litter box. Keep the door closed, and for a few days, feed them both treats on other side of door so they associate each other's smell with a good experience. Then let the other cat in Zeke's room while he is in a cat carrier. They can smell each other, but not be in contact. If either becomes upset or show signs of aggression, remove the second cat from the room, and try again later. Praise them when they interact appropriately. When they are interacting well with each other through the carrier, you can let Zeke out of his room, and see how he interacts with the other cat. Praise them when they interact appropriately, and separate them with any sign of aggression or upset. I would get a cat tree with lots of shelves to give the cats vertical space to get away from each other. I would keep Zeke in his room when you go out until they are comfortable with each other. I hope this helps.

Yes, bullying from another cat can definitely cause stress and anxiety. Pheromone products and calming food or supplements such as royal canin calm can be very helpful. Try not to encourage the other cat, ensure there is no food available for him and that he cannot access bedding areas etc

This may be difficult to correct but it generally can be done. Continue using the diffuser. Try switching litter boxes, beds, and rubbing each cat with the same towel to try to get them to smell like each other.

The veterinarian can also prescribe medications which can help with aggression. I hope this helps and please feel free to post any additional questions.

I'm sorry to hear that Nala is having a hard time with the introduction of a new kitten. It certainly sounds like she is experiencing some anxiety as a result of having a new kitten added to her household. Since it sounds like you have done a good job of introducing Simba gradually and Nala is still not tolerating him, you might need to find some ways to decrease her stress. 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 and may be beneficial for both cats. 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/ ). If Nala continues to hide in your bedroom, it may be time to take her to your veterinarian for a physical exam and discussion about possible anti-anxiety medication short-term. Hopefully if you can get her more comfortable around Simba, they can have a good relationship, but it commonly takes some time. Good luck! I hope that was helpful. Thanks for using PetCoach.

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/

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.

Oh no, that's not good! I would separate the cats, and slowly reintroduce them to each other. Take the cat who is aggressive, and put her in her own room with her own food, water, and litter box.
