Hi, and thanks for your question. As a first approach, I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken/white fish and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, more vomiting, lethargy or inappetence.
