She's had a tummy bug for the past three days but only has vomiting/diarrhoea in the mornings. She's off her food and I am having to really encourage her to drink. She has perked up slightly this afternoon but spent this morning lying on the couch fairly miserable. I've just given her a cuddle and her breath smells really strongly of pear drops. I've looking it up and it says it's a symptom of ketosis. Do I need to do anything, or is this just a normal effect of tummy bugs? TIA
