Sodium and Cat’s Diet

Sodium is an alkali metal element that plays a huge role in cats and human health alike. It’s found as in a cation (Na+) form.

It’s one of the essential elements for cats’ health. It has a crucial role in regulating its blood pressure. It also possesses a balancing effect on volumes and osmolarity of different fluids in the cat’s body.

How Much Sodium Does a Cat Need?

A healthy cat should have its plasma sodium concentration level kept at around 145 to 155 mEq/L to maintain the osmolarity of extracellular fluids in a range of 320 mOsm/L.

The lower concentration in the levels of sodium in the blood’s serum is known as osmolar hyponatremia. This can cause many symptoms such as lethargy and weakness.

However, higher sodium levels are often the more popular issue with cats. This is called feline osmolar hypernatremia, and it can cause a lot of symptoms that we’ll be discussing later on.

Moreover, the Association of American Feed Control Officials (AAFCO) suggests that there should be a minimum of 0.2% sodium in cat food to help in maintaining a healthy level of sodium in its body.

Did You Know That: excessive furniture scratching or peeing outside the litter box are signs of cat anxiety. One way to ease this stress is to use Feliway products; read on this comprehensive Feliway Diffuser review to learn exactly what this brand offers and whether it actually works or not. Alternatively, here’s another good way to stop your feline friend from peeing outside the litter box.

Why Would You Go For a Low Sodium Diet?

Healthy adult cats can utilize and manage the excretion of sodium out of their body correctly. However, with some diseases and aging conditions, some cats lose this natural ability to deal with their sodium levels.

In that case, despite being a very important element for your cat’s health, you’ll find your vet recommending lower sodium intake in your cat’s diet.

A lower diet of sodium can help in some health issues. Here are some of them.

Feline Cardiomyopathy

Cardiomyopathy is a heart muscle disease that can affect cats. Although its main cause remains unknown, it has been linked with a genetic mutation in certain species of cats such as ragdolls and north American Maine coons.

This disease causes weakness in the heart muscles, which causes the thickness of its walls. This leads to poor blood circulation and enlargement of the heart; making cardiomyopathy one of the most serious diseases in cats.

Cutting down sodium intake can help greatly in slowing down cardiomyopathy’s worst complication, which is congestive heart failure.

Congestive heart failure occurs when the heart isn’t able to pump the blood due to its severe weakness. Sodium has some water retentive properties, in which it increases the volume of water and consequently the blood in the cat’s body.

When this happens, the cat’s go through a compensatory enlargement of the heart in an attempt to push the blood through blood vessels which in turn weakens the heart muscles with time.

Less sodium means less blood volume, which eventually decreases the workload needed by the cat’s heart to distribute the blood adequately through other organs.

Feline Hypertension

Just like humans, sodium restriction is a must for cats with high blood pressure. Sodium has a direct effect on activating the Renin-Angiotensin-Aldosterone System (RAAS).

RAAS is responsible for the production of the blood pressure raising hormone aldosterone. According to many studies, high sodium consumption has a linear negative effect on cats’ blood pressure and cardiovascular health.

Kidney Disorders

Cats’ kidney disorders are also related to the Renin-Angiotensin System; in which it causes constriction to the blood vessels of the kidney’s microfilters called glomerulus.

Just like when pinching a hose intensifies its water output, the vasoconstriction also increases the pressure of the blood in the kidney. This causes long term damage to the kidney that goes as far as kidney failure.

Osteoporosis

All electrolytes are connected in a cat’s body. Sodium is one of these electrolytes and its increase will always cause a disturbance in some other mineral or electrolyte.

In the case of excessive sodium intake in the cat’s diet, blood calcium replaces sodium in urine (which is known as calciuria). This urges the body to draw calcium from the bones to compensate for the blood calcium loss.

Dehydration

Last but not least, excessive sodium intake leads to greater water loss through urination. Our bodies can deal with dehydration simply by making us feel thirsty so we drink water.

However, dehydration can be more problematic for cats; as cats have much less urge to drink water than humans. Dehydrated cats will always look weak, have a lower appetite, and usually suffers from higher heart rates that can turn into a cardiac disorder.

Top 3 Low Sodium Cat Food Brands on The Market

While there are many brands that offer regular cat food, there aren’t many brands that produce specialized diet food.

To make things easier for you, here are some of the top brands that offer low sodium cat food.

Hill’s Prescription Diet might be one of the oldest brands in the field. In the late 30s, the company’s Co-founder, Dr. Morris, started making specialized diets for pets who suffered from malnutrition.

In the company’s lab, Dr. Morris produced several prescription diets in 1951. Today, after 70 years of experience, the company still produces some of the best formulas on the market.
