we still got her brother and he is feeling the loss too so sad
nheather said:My experience.
We had two cats, a ginger male and a black\white female, not brother and sister but aquired together when they were both kittens. The female was always shy but got on with the male.
At the age of 3, the male was killed when hit by a car.
We have since got a tabby male kitten - he was 8 weeks when we got him.
He is very friendly and inquisitive. We followed all the instructions about keeping them apart and introducing them slowly. The new kitten wants to be friends but female isn't having any. She doesn't fight him but she cackles, fluffs her tail and eventually runs off.
The sad thing is that she will hardly come into the house now and we hardly see her. We keep hoping it will improve but it has been going on 2.5 months now. I worry what will happen when the weather turns cold and wet.
Obviously, all cats are different, but something to bear in mind.
Sometimes, getting a completely different type/breed/colour of cat, is the better solution/option. That way, your kids (and you too) won't be constantly comparing it, to the beloved pet you've just lost.
Sorry to hear that mate my cat is about 9 years old now, I do dread the inevitable day
