These signs could be just dietary related or compatible with a gastrointestinal inflammation/infection. I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken (or 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. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
