Sada is an absolute cutie, no wonder you wnat to keep her
She's probably just eating so much cos the wee soul isn't sure when her next meal is, I get so mad at the thought of people dumping aniamls, I mean she is so cute, how could they?!?! There is absolute no excuse for it, there are plenty of shelters and shops to put notices up etc. I hope whoever dumped her comes back as a mouse next time and finds themselves with loadsa cats roundabout, that'll teach them
