Anemia in cats can be dangerous, but it’s treatable – here’s what you need to know

Anemia in cats: Guide to causes, symptoms, treatment, and prevention

By

Anemia isn’t just a human condition; your feline friend can suffer from it, too. Anemia in cats happens when the number of red blood cells (RBCs) falls below normal levels. The condition can occur for several reasons, including inadequate red blood cell production, destroyed red blood cells, or blood loss.

Though anemia in cats is treatable, it carries risks and requires special care from a veterinarian. What’s more, only a vet can diagnose anemia, but you may recognize some common red flags. If you think your cat is suffering from anemia, it’s essential to visit a veterinarian for medical attention. The sooner your pet receives help, the more likely it is they’ll have a positive outcome.

Types of anemia in cats

Anemia can be divided into two broad foams: Regenerative and nonregenerative:

  • Regenerative anemia happens when the bone marrow attempts to respond to the reduced red blood cent count by producing new RBCs. Examples of this type include hemolytic anemia and blood loss anemia.
  • Nonregenerative anemia occurs because the bone marrow has failed to produce new RBCs to replace those lost. It occurs due to kidney disease, bone marrow disorders, poor diet, and other chronic diseases.

It’s vital to note that multiple causes of anemia can be present in your pet. This tends to complicate the case, but it’s wise to listen to your vet’s advice.

Causes of cat anemia

KeepBear in mind that anemia is usually a symptom of many other conditions. Therefore, it can occur due to several reasons, as shown below:

Causes of regenerative anemia

  • Blood loss
  • Hemolysis
  • Toxins
  • Infections
  • Genetic diseases

Causes of nonregenerative anemia

  • Poor diet
  • Kidney diseases
  • Chronic diseases like liver disease, cancers, and adrenal disease
  • Bone marrow disorders like feline leukemia virus and cancerWhite and gray tabby sleeping

Signs of anemia in cats

The common signs of cat anemia include the following:

  • Weakness
  • Increased heart rate
  • Pica
  • Jaundice
  • Paleness
  • Pale pink or white gums
  • Loss of appetite
  • Drinking water excessively
  • Lethargy

In addition to these signs, your cat may also show symptoms of an underlying disease, such as kidney disease, that’s causing the anemia. Cats that develop anemia gradually tend to show few signs until when the condition worsens.

Diagnosis of anemia

During your visit to a pet’s clinic, the vet will take a blood sample from your cat. The sample is placed in a machine that counts individual cells. Alternatively, the vet can carry out the packed cell volume (PCV) test to observe RBCs’ volume in the sample. The vet will use the test results to confirm that your cat has anemia. He or she will also use the results to determine whether the anemia is regenerative or nonregenerative.

Treatment: Increasing your cat’s red blood cells

Treating anemia in cats is usually specific, especially if your pet has an underlying condition. It can be supportive, symptomatic, or both. In supportive treatment, your cat gets a blood transfusion. This procedure is usually life-saving, particularly when the anemia is severe. Before the transfusion, the vet will determine their blood group and find a compatible donor. Severe cases might need hospitalization for easy monitoring of the condition.

Depending on the underlying condition, your vet may recommend several treatments, such as immunosuppressive drugs, antibiotics for infectious diseases, and iron supplements for iron deficiency. Some cases might also require surgery to address the underlying condition. If your cat has kidney disease, the vet can recommend long-term hormone treatments to help the kidneys produce RBCs. Steroid treatment or other immunomodulatory drugs are usually ideal for anemia that’s caused by an auto-immune disease.

If you’re looking to increase your cat’s iron, good sources include the following:

  • Lean meat like turkey, chicken, beef, or pork (trim the fat off any pork products first)
  • Fish
  • Eggs (but only as a treat and not as a staple of their diet)

Check with your cat’s vet before making any changes to their diet.

Prevention of cat anemia

They say prevention is better than cure, so here are tips you can use to care for your cat to prevent the condition:

Bear in mind that some types of anemia are preventable when you follow the above tips. More importantly, always take any new signs seriously and seek medical attention.

Final thoughts

If your cat has anemia, don’t panic. Even though some anemia cases can be life-threatening, seeking early veterinary attention can help manage the condition. It’s even possible to reverse mild cases with the right veterinary care. The recovery period depends on the cause of the anemia. Many cats respond well to treatment with optimal care.

Do cats fart? 6 causes and when to call a vet
Causes of cat flatulence and when to worry about
An orange cat's butt behind a white garden fence

It's no secret that dogs fart -- sometimes just as much as humans do. Some pooches aren't afraid to let 'em rip, but cats tend to be more shy when it comes to their bodily functions. That's why some cat owners don't even know if felines fart! Most kitties do their business in the privacy of their litter box, so it makes sense why kitty toots are so elusive.
If you've ever wondered, "Do cats fart?" but were too shy to ask for yourself -- consider your search over. We'll discuss what you need to know about feline flatulence and its causes, including when you need to contact your vet. Soon, you'll know more than you ever anticipated.

Why do cats scream when mating? Here’s what to know
Don't panic — this is a standard part of the reproduction ritual

You might get a bit traumatized when you first encounter two cats mating — be prepared for it to turn you off breeding kittens entirely. In fact, we generally recommend that you spay or neuter your animal when you don't want any babies in the immediate future. Otherwise, your pet will go into heat multiple times per year and may exhibit other unusual behaviors during this time. At the top of this list is the screaming that occurs before, during, and after feline copulation. But why do cats scream when mating? We break the whole process down for you.
What does the reproductive cycle look like in kitties?

There are four major pieces of this that start with heat and end up with a pregnancy, we hope, and this cycle is a bit different from in humans. Unlike us, kitty cats have a mating season, which can vary for a house pet, but it usually coincides with spring and summer where you live. If left to her own devices, your female cat, called a queen, will go through this full cycle many times until she gets pregnant during the season.
Going into heat
It all starts when your fur baby goes into heat. Even with no man or tomcat around, she'll likely start exhibiting certain behaviors like restlessness, calling, rolling, and something called lordosis (when she sticks her butt in the air). Even if she looks unhappy, she's really just feeling the urge.
Finding a mate
It's time for your pet to find a suitable partner, which she does with a loud scream intended to attract fertile males (boy cats often do the same to get a female's attention). Oftentimes, man cats fight for their woman's affection, though they don't really need to, as she's happy to have a go with lots of different partners.
Getting it on
Cats mate quickly and functionally. The male first grabs the female by the scruff to keep her in place and then inserts his penis, which is covered in small barbs (we'll come back to this). Both might scream during the act, and it likely feels pretty uncomfortable, at least for the girl on the receiving end. Sometimes, this ends with the queen getting her comeuppance and attacking the tomcat. Afterward, she rests for a while and then starts again.
Stimulating an ovulation
You read that right: Cats don't ovulate unless they have sex, and rarely does one shot get the job done. That's why lady cats will often begin to repeat this process soon after they finish with one tom. It also means your sweet girl can get pregnant from multiple cats at once and have a litter with mixed parentage.

Why you shouldn’t punish your cat for pooping outside the litter box
Dealing with a cat for pooping outside their box (Hint: Don't punish them)

Cats have their share of quirks — from staring at you to inviting themselves to Zoom calls. Generally, cats poop in the litter box, though. Sure, you have a box of poop in your living space (hence the tongue-in-cheek viral meme about only getting a cat if you want a box of crap in your home). You also have to clean the box. However, your regular cat regularly goes in the box, and little housebreaking is needed.

When a cat starts pooping outside the litter box, you may find yourself concerned, frustrated, and wondering how to punish a cat for pooping outside the litter box. However, you'll want to avoid punishing your cat and instead take a compassionate and curious approach. Here's why and what to do instead.
