She seems fine. She's really active at night, and I usually feed her in the evenings anyways. You'd think the smell of the guinea pigs would only make her hungrier, since she smells prey all of the time. Anyways, thanks for the thoughts guys, appreciate it. I'll try again this weekend and if she refuses again I'll wait for a couple of weeks before offering her one again. I don't want her to get into the habit of refusing food.
