Why is my cat throwing up undigested food and always hungry?

Updated on September 23, 2025

Pet's info: Cat | Mixed Breed | Female | 4 lbs

Hi I woke up this morning and found undigested cat food that looked like poop in my living room. This has never happened before. She does seem to be really hungry the last couple of days . Should I be concerned?

If it does not happen again, I wouldn't be too concerned, if the increased appetite and vomiting continue- you should take Dory to the vet in order to have a blood test done, these symptom could be a sign of hyperthyroidism.

Depending on his age these signs could be compatible with hyperthyroidism. This disease increase the metabolism and often appetite becomes ravenous and can lead to aggressive behaviour.
A clinical examination at your local veterinarian is essential to confirm this clinical suspicion and treat appropriately.

Even if your veterinarian does not find anything abnormal on blood tests, your cat may be hyperthyroid, (euthyroid sick). You may want to discuss this with your veterinarian or have your cat referred to a veterinary internist. I recommend having her thyroid tested again,

I recommend to have Mino examined by her veterinarian. An increasing appetite can be due to a few things but the two most common are intestinal parasites and hyperthyroidism. It is generally easy to test for and diagnose both of these. Treatment is based upon test results. Both of these conditions will also cause vomiting, but so can many other disease processes. It’s always best to play it safe. Best of luck.

Why does my cat throw up undigested food after eating in the morning?

I'm sorry to hear Aries isn't doing well! Unfortunately, vomiting like this can be due to a number of things, which is why a vet visit is important. Issues such as a hairball or parasites can cause vomiting, along with functional issues that may be causing problems with digestion. Other issues can include food allergies (male cats tend to be allergic to ingredients such as fish or chicken in their foods) or even an issue with how often you are feeding Aries. Smaller meals more often can sometimes help vomiting if it's every morning, especially if Aries goes all night without any food. Offering a small meal right before bed (or a treat) can sometimes keep the stomach full enough to keep it from getting too empty and causing vomiting. However, since this has been prolonged and there are so many potential causes, a vet visit is always best.

My cat ate, threw up, ate again, and threw up. Should I see a vet?

I would definitely keep an eye on him, and if he vomits again or doesn't want to eat still, schedule a vet appointment. Issues such as minor GI upset, underlying illness, hairballs or obstructions, parasites, etc can all be possible causes of vomiting, which is why it's important to have it checked out if it continues more than once. If Lando seems in any obvious distress or pain (vocalizing, pacing, attempting to go potty but can't, tender to touch, etc), then he should be seen sooner.

Why is my cat throwing up bile and food? Should I call the vet?

Common causes of vomiting in cats includes hairballs, food allergy, eating too fast, GI blockage, intestinal parasites, IBD, intestinal lymphoma, hyperthyroidism, systemic disease (liver, kidney, pancreas, diabetes), among others. You can remove her food and wait 6-12 hours to see if the vomiting stops. Then only give her small amounts of her food. If the vomiting continues tomorrow, Mochi should get checked out by her vet.

Cat throws up after eating in morning, but seems normal. Why?

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.

Why is my older cat throwing up whole kibble right after eating?

Poor Sweetie! In older cats, I would be concerned that the vomiting is caused by kidney disease, inflammatory bowel disease, a foreign body, or intestinal lymphoma. I would take her into the vet first thing in the morning. The vet can do a physical exam, routine blood tests, a urinalysis, x-rays, and possibly an ultrasound to determine what is causing her vomiting. Once the cause is found, the vet can recommend a possible treatment.

Why is my senior cat constantly hungry and only eating wet food?

Thank you for using Petco Pet Education Center, formerly Petcoach! The symptoms you describe may be indicative of hyperthyroidism or diabetes, both of which are fairly common in older cats. Tests such as thyroid hormone levels (T4 and free T4) can be performed to rule out hyperthyroidism and chronically elevated glucose levels would be determined with a fructosamine level test. These are done with a blood sample, but are not routinely performed. I would also be happy to look at any test results you have for Dylan and provide a second opinion.

Why does my cat throw up undigested food after eating but seems fine?

Colby could be eating too quickly and vomiting secondary to that. Since you have changed his food already, I would try offering him a smaller amount and see if he can hold that down, then give him the rest.
