My cat vomits and has diarrhea. Why is my other cat attacking?

Chronic diarrhea in an older cat with vomiting can be a sign of an inflammatory bowel disease or intestinal cancer. The only way to differentiate between the two disease is a surgery to take biopsies of the intestines and have them analyzed. Based on the diagnosis, the diet may be changed or vitamin supplements or steroids may be added to manage her symptoms. They will check for parasite and check her labs for any renal or endocrine disease

Acute vomiting and diarrhea, especially with poor appetite and lethargy, are certainly cause for concern. This could be caused by an infection, something stuck in Max's intestines, or a metabolic problem. At the veterinarian, they will examine him and probably take x-rays and run some lab work to look for the underlying cause of Max's issues. I wouldn't wait very long to go to the vet since Max is so young and small and so can become dehydrated quickly. See if you can get in for an exam today.

Thanks for using Petco Pet Education Center, formerly Petcoach! He is so handsome! Vomiting and diarrhea can occur secondary to conditions such as inflammatory bowel disease, dietary indiscretion, parasites, among other possibilities. I recommend that you have Kalvin evaluated by your veterinarian for further assessment and treatment. At the very least they can start him on medications to make him feel better and check his hydration status. In the meantime, keep water available at all times to try to prevent dehydration. Good luck and have a good day!

It definitely sounds like BoBo has an upset tummy. I am concerned about the amount of vomiting and diarrhea that you have described. Possible causes for this to happen acutely include bacterial or viral gastroenteritis, pancreatitis, toxic exposure, intestinal obstruction, dietary intolerance or food allergy (this would happen if he ate human food he shouldn't have or if you recently changed food or treats), irritable bowel syndrome, intestinal lymphoma, or other internal medicine issues. I think that BoBo should see a vet as soon as possible to start with bloodwork and maybe x-rays depending on the findings of the physical exam. Before you go, check around the house for anything that BoBo may have chewed on, like hair ties, string, carpet, or chemicals. You are right in not feeding BoBo anything, but encourage him to drink water, chicken broth, or pedialyte to try to maintain hydration. Cats can also get electrolyte imbalances soon after having voluminous vomiting or diarrhea. Depending on test results, your vet may prescribe medications for nausea, diarrhea, or even antibiotics and gastroprotectants. If the bloodwork shows severe abnormalities or the symptoms persist despite medications, BoBo may need IV fluids to rehydrate him and correct electrolyte abnormalities. If you have additional questions I can answer, feel free to choose a consult so we can answer them.

I am sorry to hear about your kitty! If the food appears different than the one he normally eats it is possible that perhaps there is a different additive or food coloring that has upset his stomach (or is it possible it is a different flavor even though the brand is the same). We can see some pets have GI upset from quick changes in diet. That being said, we can also see diarrhea from other causes, including GI parasites, bacterial overgrowth, inflammatory bowel disease, as a symptom of systemic illness, and more. If he is still energetic with no vomiting you could try getting a probiotic from your vet or the pet store for him which can sometimes help with diarrhea and feeding something bland for a few days (such as plain white rice and shredded boiled chicken or lean ground chicken) or picking up the food you normally get at the pet store and trying this for a few days. If he is having urgency so often he isn't making it to the litterbox, however, it is quite possible he has colitis http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=677 and will likely need prescription medication to get the diarrhea under control, so the fastest solution to eliminating the problem is to have your vet examine him!

Thanks for using Petco Pet Education Center, formerly Petcoach! There are many conditions that can result in vomiting and diarrhea and they go from dietary indiscretion which may resolve on its own to systemic diseases such as inflammatory bowel disease or pancreatitis, among others. I recommend that you have Sammie evaluated by your veterinarian for further assessment and treatment. At the very least they can check his hydration status and give him medications to make him feel better. Good luck and have a nice day!

Oh no, poor Toffee! She sounds quite sick at the moment, and her vomiting and diarrhea could be caused by a GI illness, eating something rotten or toxic, a foreign body, or pancreatitis. I see that she isn't spayed, and her symptoms could also be caused a pyometra, which is a life threatening infection of the uterus. When a cat is having both diarrhea and vomiting, it's time to see a vet immediately to prevent her from getting severely dehydrated and sicker. She does need veterinary attention now, please take her 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.
