One possibility is that your cat's symptoms could be related to the recent vaccinations and wellness checkup. It is not uncommon for some cats to experience mild side effects following vaccinations, such as temporary gastrointestinal upset. However, if your cat's symptoms are persistent or worsening, it's important to seek veterinary attention to rule out any other potential underlying causes.

Another potential cause of your cat's symptoms could be a gastrointestinal issue such as a dietary indiscretion or a gastrointestinal infection. These can cause vomiting, diarrhea, and a decreased appetite. Ingesting something inappropriate, such as spoiled food or a toxic substance, can lead to gastrointestinal upset. Additionally, viral or bacterial infections can also result in similar symptoms. If you suspect your cat may have ingested something harmful, or if the symptoms persist or worsen, it's crucial to seek veterinary care promptly.

Other possible causes of your cat's symptoms could include intestinal parasites, food allergies or intolerances, pancreatitis, or even a systemic illness.

Before taking him to the hospital, ensure that your cat has access to fresh water at all times to prevent dehydration. Monitor his behavior and make sure he is resting in a comfortable and quiet environment. It's generally recommended to withhold food for 8~12 hours to allow his gastrointestinal system to settle. After this period, you can gradually reintroduce small amounts of a bland diet, such as boiled chicken and rice, to see if his appetite improves.

However, it's important to note that these home care measures are not a substitute for veterinary care, especially if your cat's symptoms persist or worsen. If you notice any of the following additional symptomatic situations, it is crucial to take your cat to the hospital immediately:

1. Severe or persistent vomiting and/or diarrhea
2. Blood in the vomit or diarrhea
3. Abdominal pain or discomfort (indicated by vocalization or unusual postures)
4. Signs of dehydration (e.g., dry gums, sunken eyes, reduced skin elasticity)

And did he get all the vaccines? There’s a possibility of Parvo virus. If it’s a parvo virus, there’s nothing you can do at home. You should go to the vet. Parvo virus has very high propagation power. In addition, in the case of young pets, the fatality rate is also somewhat high.
