I'm not sure. She seems to be upset if there is no food in the bowl - but that doesn't necessarily means she wants to eat. Maybe since she was a stray she likes knowing there is food. She eats a lot I think. I'll measure it out but it is probably 1/2 cup or a cup of food twice a day. She doesnt' seem to care for treats yet - it is ok but really she wants FOOD. I gave her can food yesterday - about 1/2 a tiny can (or 1/4 large can) and she ate about 1/2 of it. I ended up throwing it out. She liked it but wasn't hungry after she ate 1/2 - but she seems to pig out on dry food although she grazes. She finishes it all eventually. I'm not sure. I don't want her fat but she was real skinny when I got her and she just had kittens too. I'm feeding her Purina One for sensitive systems I think. Debbie
