The olive oil worked like a charm. I have a couple of the tiny syringes from the vet so just a couple little drops while she was sleeping at around 1pm and she was 'regular' shortly after waking up.
I would hate for her to have a chronic issue in her bowels, but will keep an eye out. Citrus is something I've not given them much. I'll put it into the rotation.
I know that when I have issues the usual over the counter meds are pretty harsh. I'd wouldn't want them to feel that way. The olive oil seems like a gentle way to go...but, only on occasion. Not for chronic issues.
