Customer Question

Our 3 year old cat has been throwing up his food since 1:00 am this morning.
3 times then, and 3 times around 12:30pm today. It is just food?
Can you give me any advice?

Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

Can he keep water down?

Are his gums pink or pale/white? Moist or sticky?

If you press on his belly, does he have any discomfort, tenderness, or tensing?

Could he have eaten something he should not have (ie bones, toys, plants, chemicals, etc)?

Has he had any diarrhea?

Customer: replied 1 month ago.
Does not seem to have any of these symptoms

Thank you,

First, I am glad to hear that Frank doesn't have those other signs, but I do hope he can keep water down and hasn't eaten anything harmful. As long as he has not done so and can at least keep water down, we can try supportive care to soothe his stomach. Of course, either of those 2 concerns and we'd want to have him seen urgently.

Now in regards ***** ***** question, the food could be to blame if it was old, moldy or a new diet for him. That said, we can also see these signs with bacterial or viral gastroenteritis, pancreatitis, parasites/protozoa infections, general dietary indiscretions, and ingestion of harmful items (ie toxins, plants, non-edible items).

With this all in mind, as long as he can keep water down, we can try some home supportive care to try to settle his stomach. To start, if he hasn’t just vomited (since otherwise we’d need to rest the stomach for a few hours first), you can consider treating with an OTC pet safe antacid like Pepcid (More Info/Dose @, or Tagamet (More Info/Dose Here @ Whichever you choose, we’d give this 20 minutes before offering food to allow absorption. Of course, do double check with your vet if he has a known health issues or is on any medications you haven't mentioned. Also if you give this and he cannot keep it down due to nausea that is usually a red flag that we need to bypass his mouth with injectable anti-vomiting medication from his vet.

Once he is more settled, you can plan to try small meals of a light/easily digestible diet. Examples you can use are boiled chicken, boiled white fish, or scrambled eggs, or meat baby food (garlic/onion free only). The aim of these diets is that they will be better tolerated/absorbed by the compromised gut. Therefore, it should get more nutrients in and result in less GI upset. As long as improvement is being seen, I usually advise continuing this until the signs are settled, and then weaning slowly back to what you normally feed.

Since dehydration is a risk here, we need to keep an eye on his hydration. To check this and make sure dehydration isn’t an issue, there are a few parameters you can test. Further to checking for gum moisture, you will want to make sure his eyes are not looking sunken and that he doesn’t have a "skin tent" when you lift the skin. To see how to check these, you can find a good video HERE ( If you do see any of these signs already, then that would be our cue to have him seen before this becomes an additional issue (especially since its often dehydration that makes them feel unwell).

Overall, a wide range of agents could trigger the signs we are seeing. Bad food could cause nausea and vomiting but if he has been vomiting severely it may not be the full cause here. Therefore, we’d want to start supportive care to try to settle his stomach. Though if he cannot keep that or water down, appears dehydrated already, or doesn’t respond to the above within 12-24 hours; then we'd want to get his vet involved. They can assess his hydration, rule out fever, ensure nothing in his stomach that shouldn't be, or any sinister viruses present. Depending on their findings, his vet can treat with injectable anti-vomiting medication +/- antibiotics to settle Frank's stomach and get him back feeling like himself.

Please take care,

Dr. B.
