Thanks for using Petco Pet Education Center, formerly Petcoach! Parsley is not likely to cause vomiting. This is likely due to something else. Vomiting can be observed with conditions such as gastroenteritis, pancreatitis, dietary indiscretion, gastrointestinal foreign body ingestion and obstruction, among other possibilities. For this reason, I highly recommend that you have Chloe evaluated by a veterinarian for further assessment and treatment as soon as possible as I am afraid she is likely becoming dehydrated. They would be able to check for these possibilities and also check her hydration status and give her medications to make her feel better. Good luck!
