Understand the real nutritional needs of cats – Water

Water is the most basic nutrition

A cat can endure hunger for several weeks, deplete the body’s glycogen and 50% of the protein reserves, and even only 40% of its original body weight, can still survive; but if there is no water supply, the cat is very likely Can’t even survive a week!

It can be seen that water can be regarded as the fountain of life for cats, and it is the most important and basic nutrition. Every cell in the cat’s body needs water to operate, and body temperature also depends on water to maintain. Regardless of the digestion or excretion function, it also needs water to be moisturized. However, many cat parents believe that dry feed is the best because of convenience or misconceptions. They often ignore the cat’s need for moisture, making them lack of water day and night.

Are all cats so dumb, thirsty and don’t know how to drink water by themselves? Cats are of course not stupid, but because their ancestors originated from the lack of knowledge of water sources, their bodies have been presumed to take in the required water from the body of their prey, and the bodies of small animals,they prey are about 70% or more is water (this ratio is actually equivalent to the water content of canned cats). They are set to not rely on drinking water to replenish their water. The thirst mechanism is much slower than that of dogs and humans. Therefore, if you see a cat actively drinking a lot of water, it is actually very dehydrated.

How much is enough to drink?

The amount of water a cat needs every day is equivalent to the calories needed every day. A rough estimate is that 60ml of water is needed for every kg (cat’s body weight). In other words, if the cat’s weight is 4 kg, its daily calorie requirement is about 240kcal, and its daily water requirement is also about 240ml.

If the above cat uses 80% water-containing canned cat food as the main food, it needs to eat 3.5 cans of 70g canned food every day to provide the 240 calories it needs per day. Then, how much more water it needs to drink to meet the daily needs. What about the 240ml water needed?

Daily water requirement for cats weighing 4 kg: about 240ml

In other words, dry feed can only provide 4% of the cat’s daily water needs, and most of the water needs to be replenished by the cat’s own drinking water; but it is impossible for the cat to drink 200ml of water spontaneously.

Water provided by the can: 70 X 0.8 X 3.5 = 196ml

Water produced during the digestion process (approximately 11.5 ml will be produced for every 100 kcal a cat eats): 2.4X11.5 = 27.6ml

Cats need to drink water to supplement the water: 240-196-27.6 = 16.4ml

In addition, some studies have found that even if cats eat dry food, they drink as much as 6 times the amount of water that cats eat canned food, but the actual water intake is only 50% of cats that eat canned food. No matter how much water they drink, cats who eat dry food all day are still in a state of water shortage. It’s no wonder that more and more cats are still young, but they are suffering from chronic renal failure. It is the result of chronic water shortage. Insufficient water, be careful of urinary stones.

Many people think that if there is too much Ash in food, it is easy to cause urinary stones, but this is not the case. Studies in recent years have proved that cat urine output and urine pH are the main factors that affect the formation of stones.

If cats eat canned food as their staple food, they already consume about 93% of their daily water needs. It only needs an additional supplement of about 7%. Therefore, you see cats who eat canned food rarely drink water

The more water, the more it can dilute minerals, and it is not easy to produce mineral crystals. Therefore, to successfully prevent cats’ lower urinary tract problems, the cat’s urinary output must be increased and its urine concentration (Urine specific gravity, USG) lowered, so that crystals will not form so easily.

If the cat eats dry food every meal, the daily intake of water is not enough, and there is no way to increase the urine output. Then cats may have so many urethral or bladder stones and blockage problems in the future, and they will often recur. In fact, as long as you switch to foods that are high in moisture, your cat’s chance of recurring urinary problems will be reduced by at least half.
