Sorry I'm posting so much, but this is all happening at once. I've had Kayly for 8 months now, she's a year and a half old, and she's been living in my friend's house for two months. The whole time I'd had her, she was never a picky eater. Even when I switched her to rats, she struck and at the second it was in her line of site, even in shed. She's always readily taken food no matter the color as well. Recently, I've had to start feeding her every two weeks instead of every week because the last three times I've bought a rat, she's not cared for it until the next time we try a week later. This is not due to moving her as she started this a couple weeks before I did so. Any ideas what she's being picky about? I don't know how much she weighs as I don't own a scale, but I'm fairly certain she's healthy. Is she just now deciding on colors or something? She's eating small rats so I know her food is the proper size. What could it be?
