Hi!
Welcome!
I leave food out all day for my gang. If you are concerned about if she is eating enough, measure out how much you put out and then you can remeasure later in the day to see if she is eating well. Eating well is not an issue I have, I'm blessed that all three eat well.
I
think that if she was going to be a Parti the white would be visible from the start. But she will change color regularly for the first year and can up to 2 years. Gracie Ruth started getting silver roots on the top of her head when she was around 4 months. She is 10 months now and I'm so glad I took pictures of her every month so that I could document all the color changes. My DH has threatened Yogi with Just For Men hair color if he even thinks of getting silver.
He's hoping for the beautiful black and gold like Yogi's daddy.
