Thanks guys. Decided probably not best in the interest of both of them to attempt trial period. Burmese ended up in rescue centre due to being not well cared for and at the moment, behaviour towards other cats seem to be a result of how she was left to fend for herself. If I didn't have mine, I would gladly have taken her on..
anyone going to show in Thornbury on Saturday? will be my first as a member of public.
