My cat drank milk, has watery stool, and is scratching a lot.

Updated on September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | spayed | 7 lbs

My cat drank some whole milk yesterday and today on accident. I noticed her stool is very light brown and watery. Is there anything I can do to make her better? Also I noticed she has been scratching a lot of her hair off and has some sores. What can I do to help her get better?

Poor Princess! Cats are lactose intolerant, so that that would be causing her diarrhea. It's best to make sure not give cats any dairy products to avoid GI upset. You can try a home remedy to see if that helps the diarrhea before having to take her to the vet. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.
This scratching can be caused by fleas, mites, ringworm, or allergies. If she isn't up to date on her flea treatment, she will need a spot on treatment such as Advantage or Revolution. You will need to disinfect the environment as well. If she is up to date on her flea treatment, I recommend taking her into the vet for an exam. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment. I recommend taking her into the vet tomorrow during normal business hours.

    It could be Mae is nauseous and isn't feeling well, and if the food was out in a warm spot, that could be making her sick. Feed her a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If she vomits the bland diet, she won't eat the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. Best of luck.

    Poor Beau! Withhold food for 12 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

    Poor Ruby! It's always concerning when a cat throws up, and the effort from throwing up may have made her a bit disoriented. Her vomiting could have been caused by a GI illness, eating something rotten, a foreign body, or pancreatitis. I can give you a home remedy to try to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.

My cat has diarrhea 5 days, scratching bum. Vet or home remedy?
Hello and welcome to Petco Pet Education Center, formerly Petcoach. As long as Lola isn't having watery diarrhea, and is still eating and drinking, she shouldn't become too dehydrated. It sounds however like she might have something else going on, and dragging her bum on the ground suggests that she is itchy. I would start by deworming her, as she likely has worms. Also, make sure she is on a high-quality kitten food. If she stops eating, or becomes weak and not moving, then please have her seen by a vet right away. Best of luck with Lola.

My cat has scabs. Could her milk cause an allergic reaction? How to help?
It does sound like she is having an allergic reaction to something. This can be an insect bite hypersensitivity (such as fleas or mosquitoes) food or environmental allergy. A vet visit would be a great place to start if she is itchy or any of the lesions appear to be infected as she may need medication to feel better. I would recommend stopping the milk as this may be a cause and typically is not good for most cats. Discuss your concerns with the vet and they may also recommend a diet change but as long as she is on a good quality cat food I would not immediately change it. Make any changes one at a time so you can evaluate her response. It can take up to 4-6 weeks to notice a difference after resmiving a possible allergen. Good luck and thanks for using Petco Pet Education Center, formerly Petcoach.

My 2-month kitten has bloody diarrhea after cow milk. Vet needed?
As long as she’s feeling fine and eating and drinking she should be fine. Please get her back on cat food and water only and this loose stool should resolve without treatment. When cats have bowel irritation they can pass small amounts of blood. If she’s not eating well, not drinking or the diarrhea lasts more than a day then please take her in for an exam and treatment. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Whiskey.

Indoor cat scratching a lot, no fleas. What could be wrong?
This could be a sign of several things including environmental allergies, mites, ringworm, and food allergies. Without doing a physical examination on Shyannne it's difficult to say what it causing her to itch. Even if you are not seeing fleas, if she is not currently on a good quality flea preventative like Revolution you may want to start. You may want to try bathing with a soothing shampoo. Once a veterinarian checks her out they may prescribe a medicated shampoo. The Douxo line makes medicated shampoos and also mousses for animals that are more difficult to bathe. Omega-3s are naturally anti -inflammatory so these may help as well. If Shyanne's symptoms persist then she should be taken to your veterinarian. Her skin can be tested for mites and other types of infections. There are many treatments for allergies available as prescription medication. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope Shyanne's skin issues resolve quickly!

Vet Q & A
My cat has diarrhea, swollen nipples, and a red area when pooping.
I would recommend that you have Princess seen by your veterinarian. A rectal prolapse may need surgical correction and will get worse with time, if left untreated. Diarrhea can exacerbate a prolapse. An infection with a parasite called coccidia can cause diarrhea and causes enough irritation in some pets to cause a prolapse. Your veterinarian may recommend checking a stool sample to see if this is part of the problem. I would also recommend that you have Princess spayed to prevent future litters of kittens. Unspayed female cats are at higher risk for developing mammary cancer later in life and uterine infections.

My cat ate whipped cream and has yellow diarrhea. What do I do?
Cats are lactose intolerant and should never get dairy products because it causes GI upset. That is likely why Rex has diarrhea. I can give you a home remedy to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Best of luck.

Vet Q & A
My cat has diarrhea for 2 days and patchy hair loss. What's wrong?
I'm sorry Mrs. B has had diarrhea! This diarrhea can be caused by eating something rotten, a foreign body, GI illness, or intestinal worms. Make sure she is up to date on her deworming treatments. I would take Mrs. B into the vet today for an exam. When a cat has diarrhea for more than 24 hours, it's time to see the vet. The vet can diagnose what is causing her diarrhea, and can treat her for it. While at the vet, they can examine her for the cause of the patchy hair loss, which can be due to fleas, mites, ringworm, allergies, or an autoimmune disease. Once the cause of that is found, the vet can prescribe her treatment for it.
