It is pure liquid yes and a yellow/brown colour. It doesn't smell.
The vet did give her a laxative but 8 days ago! Would it take that long to work? Today she has been constantly in and out of the bath and she's straining way more than normal. I think she is feeling discomfort/pain now
I've phoned up the out of hours today but the vet on call is not a reptile vet and suggested calling my own vet in the morning (because she is alert and has eaten today). I can't physically get her there before 5.00pm because of work though.
