My cat ate grass and threw up red liquid. Is it blood? What to do?

I'm sorry to hear that Dylan is experiencing so much vomiting. If it is still continuing, he will need to see his veterinarian. Profuse vomiting can have several causes, but the most worrisome is a foreign body obstruction. This occurs when a cat eats something such as a hair band, a piece of string or a toy. It then becomes blocked in the intestine causing the cat to vomit. I hope this information helps!

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

Bloody vomitus is concerning. It can indicate a gastric ulcer or a very inflamed stomach wall. Since she has just had the one episode you can keep an eye on her for now. However, if the bloody vomit continues (like more than 3 times tonight), then I would recommend taking her to the ER. Do not feed her any more tonight and let her have small amounts of water if she can keep it down. If she is not back to herself in the next 24 hours then I would recommend taking her in to your regular vet tomorrow to be checked out.

The symptoms you have described including regurgitation, blood in stool, coughing and gurgling are concerning for esophageal dysfunction and gastroenteritis. The underlying cause will likely require x-rays, bloodwork, and an abdominal ultrasound to rule in or out an intestinal obstruction, inflammation of the pancreas, or primary intestinal disease including infection, inflammation or even cancer. Please follow up with your veterinarian to discuss diagnostics and therapy.

I doubt the whiskas is the issue here, it's more likely due to the pray or something else he ingested, blood in the vomit is a very serious symptom, if it happens again i would strongly recommend bringing him to a vet to get treatment.

Thanks for the images. It doesn't appear to be blood. Blood in vomitus is usually much darker. That appears to be a mix of chewed or partially digested food, bile and hair. Monitor for continued vomiting, lethargy or loss of appetite. These are symptoms that should be addressed by your veterinarian. Consider a short fast, maybe 12 hours, then offer a bland diet in small, frequent amounts for a day or two. Transition slowly to the regular diet afterwards. If Luna will allow, increase brushing or grooming to decrease the amount of hair ingested. You can also use Laxatone or PetroMalt paste to help her pass hairballs.Find either in the local Petco.

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!
