Poor Jasper! This vomiting could be due to GI illness, eating something rotten, or a foreign body. You can try a home remedy, but be prepared you may have to take him into an ER vet. I recommend withholding food for 12 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

    Poor Bean! There could be a couple of things causing this including a foreign body, GI illness, eating something rotten or toxic, severe intestinal worm count, or pancreatitis. It's actually a medical emergency when a cat doesn't eat because not eating leads to a fatty liver which is fatal without treatment. He needs to see a vet now to diagnose the cause of his anorexia and vomiting so he can be treated. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck, I hope this helps!

    It sounds like Luna is very sick and could have an infection, parasite, gastritis, etc. I am concerned that she is not eating and vomiting as young kittens can become dehydrated quickly. You could deworm her with a broad spectrum dewormer and see if that helps. Otherwise, she really needs to be treated by a vet who can prescribe medications to help control the vomiting and give fluids to prevent dehydration.

    I am very sorry to hear that Tazz is experiencing these problems, I am sure it is very unsettling for you both. There are a number of potential causes of such clinical signs, including dietary indiscretion, pancreatitis, parasite infestation, infection, and ingestion of a toxin or poison. The change in the vomit indicates that Taz's stomach is now empty and she is vomiting stomach acid. Because you have noticed these signs over the course of a few hours And Tazz is still so young I would advise having her examined by a veterinarian. In the meantime here is what you can do at home. Rest Tazz's gastrointestinal tract by holding back food for a few hours. Then you can continue with a bland and easily digested food of the boiled chicken breast and provide plenty of fresh water. If Tazz does not improve, has profuse vomiting or diarrhoea, you notice fresh blood, Tazz seems lethargic, in pain or depressed I would advise a trip to the veterinarian immediately. Otherwise, in the next day. I hope that answer was helpful and more importantly that Tazz feels better soon. Warmest regards to you both.
