Kitties can drink alkaline water only in small amounts. For your information, alkaline water has higher PH levels than a cat’s digestive system.

Therefore, in excessive amounts, alkaline water might cause indigestion issues in cats. Also, this explains why you should not give your cat alkaline water during mealtimes.

On the same note, refrain from offering nursing cats alkaline water, which can compromise their digestive systems.

Furthermore, if your kitty is on medication, don’t give it alkaline water; otherwise, the water may compromise the absorption of the medic in the cat’s body.

  • Firstly, alkaline water has acidic PH, which promotes healthy growth of your kitty’s skin and hair. The water’s astringent nature also helps tone and condition your cat’s skin.
  • Secondly, alkaline water can neutralize stomach acids (and other acids), promoting food digestion. On the same note, alkaline water flushes out acidic buildup in your kitty’s system.


  • Firstly, the high PH in alkaline water could upset your kitty’s stomach, causing nausea and vomiting.
  • Secondly, in excessive amounts, alkaline water could have unpleasant effects on your cat, including confusion, tremors, muscle twitching, and face tingling.

I recommend that cats drink water with a PH of 6.2 to 6.4 – this PH level will help boost your cat’s digestion. Of course, outside this range, your kitty will likely experience symptoms such as nausea, constipation, and tiredness.

Is High PH Water Okay for Cats?

High PH water is not suitable for kitties. It’s just that this type of water can compromise the PH of your cat’s urine (raise it to a high PH), increasing minerals that cause stones and crystals in your cat’s bladder.

Is It Safe for Cats to Drink Distilled Water?

Distilled water contains acid. In other words, it’s likely to decrease the PH of your kitty’s urine, which can contribute to the presence of crystals or stones in your cat’s system.

So, don’t let your cats drink distilled water. Instead, give the felines spring or tap or water. For your information, a good rule of thumb is that if the water is safe for you, then it’s safe for your four-legged friend.

Firstly, provide your cats with clean water always. Secondly, give them electrolyte supplements every day to boost the presence of fluids in the body.

Finally, if you’re not doing it, you might want to add wet food to their diet; wet food helps cats stay more hydrated than dry food. That includes canned fish, preferably tuna in water – not in salt.
