Hamster not eating dry food

[Maker]

The amount you feed sounds fine, I would continue to feed by scattering half and putting half in her bowl. If you can weigh her that may reassure you, if you have scales that you can zero whilst a jug is on them, put her in the jug and then you will know her weight. You can check every week to give yourself confidence.

You could try some high Calorie treats - sunflower seeds, hemp seeds, etc. If you cook any potato or rice for yourself you can give her a little see how she likes it, no salt though
