We got a cat from Cats Protection league 3 months ago. We were told that she was there because her owners had been evicted. It stated that she was 2 years old, had been neuteured and liked to go outdoors.
When we first got her she settled in very quickly. She liked to play and sometimes would scratch us or pounce on our forearms and bite. We would blow in her face which normally calmed her down.
A few weeks after we got her she was on heat and therefore had not be neuteured. We got her neuteured but obviously couldnt let her out because of that.
Over the past couple of weeks she has become very aggressive at nightfall. She has attacked my left leg with her claws and mouth twice and last night she went mental at my other half, hissing at him and trying to pounce at him. She looked very scary and we have never seen her act this way. We are not sure what caused this behaviour but we were very frightened of her (despite that fact that she is tiny and weighs less than 2kg) and shut her out of the lounge area for an hour so that she could calm down. She didnt really calm down but didnt try to attack like that again.
We are now at our wits end. We are seriously considering taking her back as we cannot live in fear in our own home. This would be hard, as I, particularly, have fallen in love with her. Tonight we are going to let her out for the first time and hope that she takes some of her aggression out on something else. The majority of the time she is very cute but doesnt like to be petted or handled too much and certainly isn't a lap cat.
Does any body have any advice please?
