Can anyone give me some advice. I have one female cat 2 years old and a female kitten 10 months old. As first they sort of got on but now my eldest is really agressive towards my kitten, none of them get more attention than the other. Its got really bad my eldest growls and tries fighting with my kitten all the time, they cant be in the same room as each other Its really not nice to see this. I just want them to get on.

Can anyone give me any advice on this

You will find this will happen...at first but hopefully they will settle down and things should improve.
I introduced a very old cat to my 2 year old cat...who had been the centre of attention since birth. Two years on and thay still have fights!!! ...they seem to get on better since i fed them seperately at different times..alternating who gets fed first. They will sit in same room but not all cuddled up like i hoped they would.
They growl and hiss at each other nearly everyday...perhaps its normal in this situation.

I had a similar problem about a year ago. But our 2 year old male visitor cat ran away because he couldn't get on with our three month old kitten.

However I've since learnt from reading cat books and magazines, that its best to keep them in seperate parts of the house for a couple of weeks and to gradually introduce them to each others smells, by introducing toys and bedding belonging to one cat to the other.

I can't remember the source of this information.

Best of luck.

We slowly introduced our kitten to our regular cat - separate rooms for a couple of days, then feeding them either side of the door for a day to smell each other and finally supervised visits in the same room.

Most of the time they are okay, sometimes they fight but it sounds worse than it really is - no actual claws, just hissing when the kitten goes a little too far. Our older cat is just used to having the run of the place and likes her peace and quiet, while the kitten likes to run around the house all day causing trouble. There's bound to be a few differences of opinion - but I think given time most cats will certainly learn to live with each other.

We even caught them grooming each other last week (for around 3 minutes before kitten took a huge swipe at the older cat and all hell broke loose!).

We have four cats, 2 older ones who are brother and sister, and then later had 2 new kittens from different parents. They hated each other for several months and gradually settled down. They now dont like each other as such, but they are aloof and tolerant of each other unless one invades personal space, which is met by a swift raised claw and a hiss....and then its ok....cats will be cats...
