I am getting my first Grey in a few weeks. I very rarely travel, but occasionally I'm away for a day or two. Is it okay to leave him with just water and pellets for a couple of days? Also do you leave pellets in his cage all the time so he can snack or is it better to feed them on a regular schedule and remove what isn't eaten. I know I have to do that with the fruits and veggies, but I leave pellets all the time for my Green Cheek Conure.
