I'm so sorry to hear that Yum Yum hasn't showed up yet, but please, don't give up! Cats are such good survivors! I hope it's not too cold in your area!

One girl in our building "lost" her cat one year in february - she had given up hope, but the cat returned after 3 weeks!

Will send positive vibes towards Yum Yum and you!

The advice given already is really good - go for it! Best of luck!
