L4H, you say Rose's dish is "only inches away" from Jasper's and Puddles. Maybe she thinks that's too close and by staring at them she's intimidating them to move away, which they do. It sounds like a domination thing to me by taking over their food. Some cats prefer to eat by themselves away from others. So try and put Rose's dish in a far away corner from the others, and see if she likes that better, and leaves Jasper and Puddles food alone. For some reason she gives more respect to Sweet Pea, maybe because SP's dominant over her?
