This will probably out me but a cat adopted from the rescue where I volunteer has gone missing in East Dulwich, London SE22 earlier this week and we are trying to get the word out as much as possible.
She was only adopted on Friday and escaped the new home on Monday so she won't be used to her new home/territory yet. She was also wearing a post-surgery cone at the time which is both very distinctive if you spot her and quite risky in case she gets it caught on something.
Will try to attach image of the Missing poster. Anyone in the area please look out for her!
