It sounds as Jixie is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get as it does sound serious, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

    Sorry to hear about poor Coco. The yellow vomit is an indication that Coco is vomiting on an empty stomach. The yellow stain is from bile staining. The fact that he is lethargic is concerning, but is expected in a disease process that causes them to vomit. If he recently stopped eating and vomited, then I would not be too concerned at this time. If the inappetence and vomiting has been going on for a day or more, then I would be concerned that he is getting dehydrated or having complications associated with a disease process. In this case I'd recommend taking him to the vet as soon as possible. Below is a link to a short article that explains some common reasons for vomiting. For now, make sure that Coco has plenty of clean water available and only offer a small amount of food. You can offer fish or anything else that you know is a tasty food for him. If the vomiting and inappetence continues overnight, then it's best to get him to the vet tomorrow. https://www.petcoach.co/article/most-common-causes-of-vomiting-in-cats/ I hope that helps and Coco feels better soon.

    Poor Phobe sounds quite ill! I see that she isn't spayed. This vomiting could be due to a pyometra, which is a life threatening infection of the uterus. A pyo is fatal without treatment. Other causes include a GI illness, eating something rotten, a foreign body, or pancreatitis. I would take Phobe into a vet now for a physical exam, blood tests, a urinalysis, and x-rays to diagnose what is causing her vomiting so she can be treated. If she does have a pyo, spaying her is part of the recommended treatment.

    Vomiting is a vague sign and common to many issues. Any cat which is fasting more than 24hours, particularly if older and/or overweight should be checked by a vet as the fasting can cause additional complications on top of the original cause. Try offering warm, soft food and pedialyte and arrange a visit if not improving
