Adopted cat becoming more and more agressive?!?

post #1 of 4
Thread Starter 
Hi folks,
first of all, I'm new to this site so I apologize if I ask a question that has been asked a million times before.
I'll tell you the cat set-up in the house. It started with my old cat Pinky (female), who's now about 14 and is quite gentle. Then we have a 3 yr old boy cat named Charlie, who's a bit of a bully.
Around Xmas 2008, a tortoise shell cat started hanging around in the back yard and as she looked so miserable, we started feeding her although it was impossible to pet her and she was hissing at all humans (but not at the cats).
She ended up coming round every day to be fed and we soon realized she was pregnant. She seemed to live in a house near us but her owners just threw her out when they went on vacation and even when they were about, she was treated as an outdoor cat and they were throwing bits of chicken on the floor for her to eat from time to time.
She had kittens in their yard and we assume they were given away as we saw them for about 6 weeks and then nothing.
Then last year in the fall, she started coming round to our house every day again, pregnant again, and the next door neighbor said he was gonna adopt her and when she had her kittens, 1 was given away, the neighbor kept 2 and we kept 2 girls (also tortoise shells).
However, although the neighbor did a good job with the kittens, he threw the mom out after a while, claiming she was agressive towards him and the kittens he kept. She ended up getting pregnant again and had her kittens in my bathroom (6!). My husband and I looked after her and her 6 babies until we found good homes for all the kittens and then we had her fixed (as are all our other cats).
At first she seemed grateful and although she's a tortie, she was quite sweet, sleeping alongside me on the couch etc... grooming her 2 older daughters that we kept and she seemed to get on well with the other cats, except for Charlie but they were just ignoring each other.
Then little by little she became more agressive and she just gets worse every day. She now cannot stand any of our cats, she will hiss at them as soon as she sees them and just gets startled at any noise or any sudden move. She doesn't quite attack them but she'll give them a wide berth and will sometimes raise her paw at them.
She strated being agressive towards us as well. Sometimes she'll quite happily let us pet her a little and then will bite and scratch very bad without warning. Once I leaned towards her and she jumped at my head and scratched my scalp, there was a lot of blood running everywhere. My teenage stepkids are quite weary of her as she just turns from one extreme to the next.
Just a few weeks ago she was grooming old Pinky, now she'll just hiss at her!
I saw Charlie jump on her and attack her a couple of times, could that have made her scared of ALL cats and humans? She has known us for almost 2 years now and always asks to be let in and to be fed. Surely if she was really scared of us all she wouldn't come in?
Dunno if it's a bad case of 'tortitude' and dunno what to do to make her feel more relaxed, at least the way she was 6 months ago.
Has anyone ever encountered that kind of problems?
Any help will be appreciated. Many thanx.

Welcome to TCS, Scarletwoman! We're glad you're here, if sad for the reason you've arrived.

Cats that are sick can turn aggressive. Other cats that sense a sick one can turn aggressive toward that one (survival instinct - drive off the sick cat so it doesn't bring predators around). Both the fact that Charlie once ignored her and now attacks her and the change in her behavior toward you kinda lead me to think there might be something wrong with her.

Has she been seen by a vet recently? If not, can you bring her in for a thorough checkup?

Also, have there been any changes in your routine in the last six or seven months? New job, new schedule, new house guests?

Any strange cats hanging around?

All of these can trigger stress, which sometimes leads to aggression.

Is the cat fully indoor now, or both indoor/outdoor?

Hope you figure out what's wrong with your tortie!

Hi Auntie,
the cat was checked when she went in to get fixed in May. Nothing has changed since, no new job or house guests. Cats in the neighborhood come and go but most of them have been around for years.
We used to let her stay indoors most of the time but due to the size of our apartment and her increasingly odd behavior, she now spends a lot of time outdoors. But they all do, especially with the good weather.
It was raining a few nights back and I let her in for the night. She stayed in the lounge with my 17 yr old stepson but he didn't get a lot of sleep as she kept hissing everytime anyone moved! She usually begs to be let in at meal times and will occasionally spend some time around me when I'm at the computer. But although she seems to seek reassurance from me, she won't let me too close, she's very temperamental.
She's had ups and downs over the past 2 years and it feels like a huge setback now that she's hissing and growling at everyone when she was friendly-ish a couple of months ago.
I don't wanna give up on her as she's been unlucky with her humans in the past but my husband doesn't have a lot of time for her.
We're planning to move within a year or so and I don't want her to come back to a closed door or some strangers one day. At the same time, she loves our garden and the gardens nearby and I worry she would be even worse in a new environment.
Thanks for your suggestions.

All of my experience has been with indoor-only cats where the environment has been somewhat controllable.

As an outdoor kitty, she's exposed to so many different things, I couldn't even begin to guess what's caused the change.

Given this set of circumstances, my first step would be to take her to the vet for a physical. (My next step would be to bring all the kitties indoors permanently, but I know not everyone agrees with this or is able to do it.)

There are many knowledgeable folks on TCS; hang tight and I'm sure someone will come along soon with some additional recommendations, suggestions or "this is what happened with me"s.

In the meantime, many calm-down and be-well vibes to your kitties...
