Introduce my new cat is really hard. Could you help please?

[Hetyu]

We have a 9 month old castrated female cat. 4 days ago we bought a a 5 months old male who is not castrated yet. They are both sphynx cat.
The problem is that whatever We try to do the older cat is always chasing the new one and, hitting and biting Him.
They are living in different rooms because We have read about the problems about new cats. On the 2nd day we let them smell each other, they were hissing and fighting occurred...
2 days past, they are still living in different rooms so they can not interact with each other, but can feel the other. Only thing is changed from day2 is that hissing is stopped and sometimes the younger one attacks back...
We have tried to be more kind with the older one but whatever We do to her she attacks in the very moment when she see the newcomer... Giving them delicious "junk" food or trying to let them play together not works here...
We need help. We do not want to sell the new cat that we have just bought.
Help please!

You are doing everything right, your female is just defending her territory. Just keep letting the new cat out for short periods. If your old cat hisses, that's fine, but if she growls or attacks him (or the other way around) put him back in his room. Just keep doing it for longer and longer periods of time, and they will get used to each other. They may not be best of friends, but as long as you don't see blood, you're doing fine.

You should get your new cat neutered soon, or he will start spraying urine in the house. It may help with aggression, as well.

There's a product called Feliway that has synthetic pheremones in it that help calm cats. I like the plug-in diffusers best, but there's also a spray. It's not a necessity, but if you can find it, it is useful.

Good luck to you, and congratulations on your new cat!

It can take up to two weeks for the cats to get used to each other. Letting them be around each other ever day supervised is a good thing and your 5month old fighting back is just standing his ground to her which is a good thing to because they are seeing who is more dominant like the alpha of the pack. Give it time and don't give up. And I would recommend getting the male fixed asap before he starts learning to spray

I can totally relate! I now know to separate them for at least a week as hard as it is. they can smell each other and put their paws underneath the door to play. Even after that they are still going to go through the stage of getting to know one another. I have had my eldest for 17 years. She's declawed and is a little on the frail side and yet she beat up on my new cat that was young, strong and had claws. that cat screamed like she was being killed and all my cat did was smack her with her clawless, soft paw! It's the pecking order and it can take MONTHS before things will calm down. I would only be concerned if a lot of biting occured that cause injury. If your new cat isn't really being hurt let them work it out but maybe separate them at feeding time to give the new cat some rest and relaxation. Cats are very territorial, your new cat needs it's own space.

We introduced a 6 week old kitten to a 6 year old female and we had the same problem, but by putting the two cats apart they'll never get use to each other they need to be left to get on with it by themselves you should only intervene if one is really hurting the other mine have only really started to get along now after 7 weeks we have the kitten in a separate room at night to give the older one some peace and this seems to help but yours need to sort out who is top cat if you keep removing them they never will you just need to be patient and given time things will work out fine..
good luck

You are worrying for nothing lol. It is common, New cat comes in house, they hiss, chase and smack each other. If it isn't an all out cat fight, don't worry. In a few days, one will be the lead, the other will follow, know it's place and they will be fine.
I have 4 cats. Went through this with all of them. The only time problems may take longer to solve is if an older one household cat is introduced to a new one.because the older one has been number one for so long.
It will work out just fine.

Cats are funny animals, the older female probably feels that the younger male has invaded her territory and wants to show who is the boss - more info here - http://www.petsnanny.net/why-cats-fight.htm
