As long as she's not getting fat she's fine I've recently learned what a "fat" snake looks like, but just can't describe it... you almost see like a double chin... ok, all you experienced folks can laugh at me now! Anyway, just go by how she looks and acts. I think you're at a good starting point. You could probably stretch that meal to once a week and you could probably switch from pinks to fuzzies. Fuzzies are a bit bigger than pinks, but if she's eating two to three pinks she can likely handle a fuzzy. Fuzzies have less fat than pinks so will put on weight a little more slowly.
