Kitties can be such a pain in the bum. They don't realise how much we care about them, and how we get when they are not about.
I'm relieved that it wasn't Phoebe, but upset that someone else is having pain.
I'll send positive thoughts to Phoebe and lets hope she suddenly thinks hang on a minute your not my Mum, and comes home where she belongs. Just keep trying, don't give up hope (I know you won't). Carry on going out calling and shaking those biscuits, and even if she is tucked up somewhere safe and warm she'll come running to you.
you and Phoebe are in my thoughts xxxxxx
