As long as it's the space between her eyes, if she seems to have trouble pooing then you may want to drop it back down a size. She is eating her greens lol well nibbling is a start that's good to hear she has to get used to them. I've never fed spinach I use the nutrition chart Tonja gave on the first page and stick with the green and black items, and once in a blue moon a blue item , I just am a worry wort lol. Of course she likes what she shouldn't have, I love salty things but I'm supposed to do a low sodium diet
