No movement

You said I needed smaller prey.. could I cut the rat at about 3/4ths?

No...don't do that, snakes have a hard time trying to swallow such things, it's likely to fail.

And I didn't exactly say that...I'm not seeing the size of your prey item next to the size of your snake, so it's hard to judge "from here" (online).

What I meant was she should be on smaller prey than you might otherwise assume she'd eat. In other words, don't try to feed her something that's the same size as her mid-body- I doubt she can handle that right now- it would be best to feed her once a week on smaller & more digestible items (mice even, if available) IF she'll eat them for you, so she can replenish her skinny body. She will need to gradually build up to eating the size rodents recommended in the feeding chart.
