Is my cat's vomit bloody after a hairball? Should I worry?

While vomiting hair occasionally is normal for some cats the increased frequency you have described is concerning. It is possible at Midnight is grooming more due to a seasonal coat shedding or she may have some underlying intestinal irritation contributing to the vomiting. Cats that hunt are at higher risk for parasites and this can also contribute to vomiting. If the increased frequency of vomiting continues or if you notice any other signs such as decreased appetite, lethargy or weight loss, I would recommend that you have her seen by your veterinarian. They may recommend checking a stool sample for parasites and possibly blood work to rule out other potential causes for vomiting such as kidney disease or thyroid problems.

It's possible Luna may just have some minor GI upset, or she is going too long in between meals if this has only happened twice and she is otherwise normal and happy. Other possibilities can include something such as a hairball that is leading to vomiting. Offering a bland meal after she vomits, or increasing the number of meals she gets per day may help with anything minor. If the vomiting continues, worsens, she shows other signs of illness, or you are just very concerned about it, it is always best to schedule a veterinary visit to rule out more serious issues. Internal parasites, GI illness, metabolic diseases, etc can all potentially cause vomiting as a symptom, so a complete exam is best to rule out any more serious problems.

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.

I strongly recommend getting your cat seen by your vet right away. Lethargy is a worrying sign after such an incident and she must continue to eat or she can develop liver disease in a matter of days. There may be more hair that cannot get back out or that may be causing an intestinal blockage. If this is the case, without treatment it can be life-threatening. Your vet will do an exam, x-rays, possibly lab work, and base don these results will be better able to tell you what is wrong and how best to treat it.

This could just be digested materials mixed in with the hair. I wouldn't be too concerned. I would however get him started on hairball medicine regimen a few times per week. I like laxatone. You can give it 2-3 times per week long term. If the vomiting continues or if you ever see blood, I would have your vet take a look at him. I hope this helps!

This could be dirt she ingested with the hair when she was grooming, or she ate something that was, for example, burnt or charred and is not digestible. It is not something to worry about, in my opinion. Since your kitty obviously is a good groomer, I suggest you get a tube of hair ball remedy and give her some regularly to help with elimination of the hair balls. There is also dry food with hair ball control ingredients.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Mushu and for providing pictures, they are helpful. It may be he is grooming himself a lot causing the hairballs and leading to the vomiting. I would start brushing him daily to see if that helps with the vomiting. If it does not, then I would have him seen by a vet. I hope this helps!
