Live in a caravan with our cat. For the last 3 days her motions have been mustard coloured, slightly mucousy and not firm. She seems fairly happy and doesn't meow excessively.

It sounds like Molly may be experiencing some diarrhea. This can be caused by intestinal parasites, eating something rotten, a foreign body, or a GI illness. When a cat has been having loose stools for more than 24 hours, it's time to see a vet. I would take Molly into a vet today, and bring along a sample of her stool for the vet to examine. The vet can diagnose what is causing this loose stool and can treat her for it.
