Why did my outdoor cat vomit blood after eating prey and new food?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. I would recommend withholding food for at least 8 hours and then initiating a bland diet as outlined below. The blood is likely due to gastritis with irritation in the stomach / GI tract. If the vomiting does not resolve or it worsens, I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps and that he feels better soon! Please let me know if you have any further questions or concerns and I would be more than happy to help you further. GENERAL INFORMATION A bland diet is a diet that is soft and highly digestible. It is low in fiber, fat and protein and is high in carbohydrates. Bland diets are generally composed of a single carbohydrate source and a single lean protein source. The most common bland diet is boiled rice and boiled lean chicken breast, without skin and bones. Since bland diets are low in fiber, stool production slows and defecation is less frequent. Bland diets are fed to rest the gastric system and to help promote normal stool formation. Animals that are physically sick should not be fed bland diets as a method of treatment. PRIOR TO FEEDING A BLAND DIET Pets should be fasted for 12 to 24 hours. Young animals should not be fasted for more than 12 hours. Fasting will allow the intestinal system to relax and minimize acid secretions that may irritate and inflame the intestinal lining. During the fast small amounts of water or ice chips may be provided. Never fast a sick animal, it may cause disease progression and death. BASIC BOILED RICE AND CHICKEN BLAND DIET RECIPE CARBOHYDRATE SOURCE: Boiled white rice LEAN PROTEIN SOURCE: Chicken breast, no skin and bones BOILED RICE: 1 part white rice with 3 parts water boiled for 20 – 25 minutes or until the rice is easily crushed. BOILED CHICKEN: De-fat chicken breast and boil in water for 10 – 15 minutes or until the chicken meat is easily pulled apart and cooked all way through. MIXING INSTRUCTIONS: Finely chop the lean protein and mix 2 cups carbohydrate source and ½ cup lean protein source. STORAGE INSTRUCTIONS: Bland diets can be premade and stored in the refrigerator for a maximum of 48 hours. The bland diet can be cooked in a batch and frozen in feeding sized portions to minimize preparation time. Thaw and warm the frozen diet prior to feeding. PERMITTED LEAN PROTEIN SUBSTITUTIONS Pork loin, egg whites, low fat cottage cheese. 7% low fat hamburger, plain low fat yogurt. PERMITTED CARBOHYDRATE SUBSTITUTIONS Boiled potatoes, boiled spaghetti, Minute rice. PERMITTED COMMERCIAL BLAND DIETS Science Prescription Diet I/D, Eukanuba Veterinary Diet Low Residue, Royal Canin Veterinary Diet Intestinal HE. FEEDING INSTRUCTIONS Estimate 25% of your animal’s diet and feed that amount of the bland diet every 6 – 8 hours. Smaller animals will require less and larger animals will require more adhering to the same carbohydrate to lean protein source ratio. The bland diet should be fed for 4 -5 days with no treats or other food sources until stools are firm. TRANSITION BACK TO A NORMAL DIET Never transition back to a regular diet rapidly. Transition back to the regular diet over a 1 week period. Start by adding 25% of the regular diet to 75% of the bland diet and feed that combination for 2 days. If stools continue to be firm then continue substituting the regular diet in 25% increments and feeding the combination in 2 day time intervals until the diet is 100% regular diet. Minimize treats for 1 week after moving the diet back to 100% regular diet.

The irritation from the coughing and the grass blade can cause a little blood from small blood vessels that have burst. Don't worry at the moment but if the coughing or spitting up blood continues then it should be examined by your vet as there may be another one lodged.

I'm sorry to hear that Hercules is not feeling well! I understand your concern for your little guy. You did the right thing by first withholding food after he vomited. However, the blood in his vomit is a bit more concerning. It could indicate irritation or ulcers in the esophagus or stomach, parasites, rat poison ingestion or blood clotting disorders. In young cats, one of the most common causes of recurrent vomiting is an intestinal or stomach foreign body obstruction. At this point, I recommend taking Hercules to his vet urgently for an exam and he may need abdominal x-rays and/or blood testing to get to the bottom of things. I hope that he feels better soon!

I am sorry matcha is not feeling well. I would recommend trying to find a veterinarian and take him in as soon as possible. Vomiting with blood can happen secondary to gastric upset , toxins and even foreign material. It is best he gets looked to determine the cause and provide proper treatment. In the mean time I would offer good and a bland diet to help calm his stomach. I hope that helps

Poor Sebastian! While this vomiting could be caused by his food, if he's been on it a while, then it's more likely caused by something else. Vomiting and blood in the stool can be caused by a severe GI illness, a foreign body, severe intestinal parasite infection, GI ulcers, or exposure to toxins. Because blood in the stool is not normal and can be caused by serious illness, it would be best that he is taken into a vet now for an exam. The vet can diagnose what is causing the vomiting and bloody stool, and can treat him for it.

Hello! My name is Dr. Shines and I am worried about Beans. I agree that looks like blood from the photo. Just like humans, throwing up blood can indicate a real problem. Any time a pet vomits blood, they need to be examined by the veterinarian. I recommend to have Beans examined today. Vomiting blood could be due to a bleeding ulcer, severe infection, severe parasites, bleeding disorder, severe pancreatitis, cancer, a foreign object or poisoning. This may not be an exhaustive list. Sometimes it can be related to rupturing a blood vessel from severe vomiting. In that case, medication is given to protect the damaged tissue until it can heal. Bring in a sample of fresh stool for testing. Fingers crossed it's something on the less severe side and that Beans recovers quickly! And please feel free to check back in with any further questions.

It is possible Princess ingested part of the bird which is causing GI upset, or some other illness. If she continues to act ill, keeps vomiting, or shows other signs of illness it would be best to bring her to a vet as birds can carry diseases and other parasites which may cause illness, and ingesting bones or other bird parts may cause GI upset or obstructions.
