From the owner of 3 cats, I would strongly recommend getting more than 1. My 3 are mum, dad and son, and they constantly ply together, run about the house chasing each other and generally are really really happy. Having had only 1 cat when I was younger, I did find it was very loving but a little arrogant. There personalities definatly come out when there is more than 1. Also if you are out of the house for long periods of time, you will feel happier knowing that there are 2 together rather than 1 alone.
Word of warning, my 3 are all Burmeese, I got the older 2 from the cats protection league and then along came thier son, they are a really really vocal breed. They constantly talk to me and to each other.
Happy Choosing, hope all goes well. x
