Formy cat urine

If you see foamy cat urine but no other clinical signs of disease, it could be due to a food allergy or an increased concentration of proteins in the blood that are excreted by the kidneys as part of their normal function.

The foaminess comes from uric acid crystals that form in their kidneys, which can be seen on x-rays as well. The crystals are made when the cat’s body produces excess uric acid, which is normally eliminated by the kidneys into urine.

What causes foamy urine in cats?

Foamy urine is usually a sign of a urinary tract infection (UTI) in cats, but it can also be caused by other factors. In some cases, the cause of the foam may not be apparent and will require further investigation. It always best to call your vet when you think there is something wrong with your cat.

There are several possible reasons why cat’s urine might turn foamy:

  • Urinary tract infection (UTI). A UTI can happen to both male and female cats. The bacteria that cause UTIs are common in both sexes. But they’re more likely to affect female cats because their urethra is closer to their anus than male cats. Which makes it easier for bacteria from the anus to move up into the bladder and cause infection.
  • Urinary stones, crystals or gravel (uroliths). These are solid masses made up of minerals such as calcium oxalate or urate that form within the kidneys or bladder
  • Foods high in protein: If your cat eats a diet rich in animal protein, it could cause the formation of bubbles in his urine. So, if your cat has been eating more meat lately and suddenly develops foamy urination, this might be the culprit.
  • Feline idiopathic cystitis (FIC): This condition occurs when there’s inflammation of the bladder wall without any underlying cause being identified. FIC can cause blood and mucus to enter the urine, which can result in foam formation as well as painful urination for your cat.

A UTI is a bacterial infection that causes inflammation of the bladder or urethra.

Why Is There White Foam in My Cats Pee?

It is not uncommon for cats to have a white foam in their urine. This can be a sign of many things and it is worth getting your cat checked out by a vet.

It can be an infection, stones or even just stress. If your cat has been ill recently or has been stressed, then this can cause the urine to foam up.

The presence of white foam in your cat’s urine usually indicates that bacteria have entered the urinary tract, causing an infection.

If you are worried about your cat’s health, then it is best to get them checked out by a vet who can give them the correct medication if they need it. If the problem persists, then you should see your vet again as soon as possible.

What Does Foamy Cat Urine Look Like?

Foamy cat urine is cloudy and white, just like the milk you put into your coffee. It can also look yellow, green, or brown. Foamy cat urine is usually watery, but it might also be thick and frothy. It may have a strong odor.

Is It Normal for Cats to Have Foamy Urine?

No, but it’s not always an indication of a serious problem.

If your cat has been peeing a lot and you’ve noticed that the urine is foamy, it’s important to know if this is normal. Not all cats have foamy urine, but it’s not uncommon for them to do so.

There are a few different reasons why your cat could have foamy urine. The most common one is diet-related, and you can usually get rid of this type of foamy urine by changing how much water you give your cat and what kind of food you feed him.

If your cat has foamy urine but doesn’t seem ill otherwise, it may simply be a harmless side effect of eating certain foods or drinking too much water.

If your cat is otherwise healthy but has been acting strangely lately such as hiding from you, then you should take him or her to the veterinarian right away so they can check for any underlying medical conditions that may require treatment.

Foamy Cat Poop

Why is cat poop formy?

Foamy cat poop is usually caused by a gas called hydrogen sulfide, which is produced by bacteria in the digestive system. Hydrogen sulfide can be released in small amounts from the body during normal digestion. But sometimes it can be released in larger amounts, causing a foamy appearance to the stool.

Foamy cat poop is sometimes caused by constipation or diarrhea, but it can also be a result of something more serious like heartworms or pancreatitis.

Many cats suffer from constipation and other digestive issues, so it’s important to know the signs and how to treat them.

Other Possible Causes of Foamy Cat Poop
  • Intestinal parasites. Intestinal parasites like worms or giardia can cause diarrhea and vomiting in cats, which can lead to foamy cat poop.
  • Allergies and irritable bowel syndrome (IBS). Food allergies or IBS can result in diarrhea and vomiting that may cause foamy stools.
  • Diet change. A sudden change in diet can cause diarrhea and vomiting along with foamy stools. However, this is usually temporary as your cat’s system adjusts to its new diet over time.

Another cause could be lactose intolerance or milk allergy in cats who are fed milk products (including some canned food).

Cats do not have the enzyme required to digest milk sugar (lactose) so they cannot properly absorb it. This causes gas in the gut which results in foamy poops!

Tips For How to Cure Foamy Cat Poop

1. Make sure your cat is eating enough fiber

The most likely cause of foamy cat poop is a lack of fiber in your kitty’s diet. The best way to make sure they’re getting enough fiber is by adding more high-fiber foods to their meals. You can do this by adding more vegetables and fruits (like broccoli or apples), as well as whole grains like brown rice or quinoa.

2. Check for parasites

Another reason for foamy cat poop could be parasites such as roundworms or hookworms that can live in the digestive tract of both dogs and cats. If you suspect your pet has parasites, talk with your vet about treatment options!

Your vet may prescribe you a dewormer for cats.

How Do You Treat Protein In Cat Urine?

Protein is one of the most common components of urine. It can be found in normal, healthy cat urine as well as in urine that is a sign of disease.

Proteinuria, or increased levels of protein in the urine, is often caused by kidney disorders. But it can also be due to other conditions, including pancreatitis and urinary tract infection (UTI).

The best way to treat protein in cat urine is to feed a high-quality food that has no filler ingredients and uses whole meat proteins instead of by-products or meat meals.

This means you will have to pay more for your cat’s food, but it is worth it in the long run because you will save money on vet bills due problems that arise from using poor quality foods.

The most common cause of protein in the urine is glomerular disease, which refers to damage to the kidneys’ filtering structures called glomeruli. Glomerulonephritis. An inflammation of these tiny filters is one cause of glomerular disease.


The most common cause of foamy cat urine is urinary tract infection (UTI). A female cat’s urethra is much shorter than a male cat’s, which makes it easier for bacteria to enter the bladder.

The UTI can be caused by stress, diet, or even a urinary obstruction. If your cat has a UTI, it will likely have other symptoms such as straining to urinate, blood in the urine, and painful urination.

You should take your cat to the vet if you notice foamy urine. Your vet will prescribe antibiotics and possibly recommend dietary changes to help prevent future UTIs.

In fact, cat’s urine turned foamy is the result of its unique pH levels. Their highly acidic urine can lead to a variety of health issues.

Including crystals in the urine, high blood pressure, diabetes, and more. If you notice that your cat’s urine has become foamy, consult a veterinarian immediately.
