Good for you for taking care of that sweet little angel! Don't let anything bad happen to her now!

As far as the food question, I say let her eat as much as she wants....she will know when she's full. My cats have food out all the time and only eat when they're hungry, they're much smarter than you might think. Also, did you have to REALLY litter train her? Most cats know to go in the box by instinct. If she had an accident on the floor, she either couldn't find the litter box, was upset, or may have some sort of digestive problem.

Good luck with your new baby, she's adorable! I look forward to seeing more pictures!
