Is It Safe for Cats to Drink Tap Water?

Part 1: The Dangers of Cats Drinking Tap Water

1. Excessive Bacteria

Tap water is home to a multitude of microorganisms, despite the extensive purification processes at water treatment plants. The water must traverse numerous pipes and reservoirs before reaching our homes, many of which have been in use for a considerable time. This can lead to bacterial buildup, which, when ingested by cats over a long period, can result in gastrointestinal discomfort, such as diarrhea and abdominal pain.

2. High Mineral Content

Tap water often contains high levels of magnesium and iron ions, which can interfere with the absorption of other nutrients and increase the risk of urinary tract stones in cats. Additionally, water treatment plants often add large amounts of chlorine for disinfection, which can react with various substances in the water, producing additional chemical byproducts. Overconsumption of these can place a significant burden on a cat's body.

Part 2: Is Mineral Water a Suitable Alternative for Cats?

Many people mistakenly believe that cats cannot drink untreated water, so giving them mineral water should be fine. After all, mineral water is for human consumption, right? Wrong. Mineral water also contains high levels of magnesium ions, and drinking it can increase the burden on a cat's kidneys and raise the risk of urinary tract stones.

Therefore, providing cats with boiled water is the most economical, practical, and safe option. Boiling water to 100 degrees Celsius can significantly reduce bacteria levels and evaporate chlorine ions, making it less likely for cats to develop urinary tract stones. This is a winwin solution.

However, the importance of adequate hydration cannot be overstated. If a cat prefers tap water or if a shelter with limited resources cannot provide boiled or filtered water, tap water is still an option to ensure the cat stays hydrated. But remember to schedule regular deworming and take your cat to the vet for checkups.

Although the likelihood of parasites in tap water is low, it's not zero. So, if your cat frequently drinks tap water, make sure to deworm them regularly. Also, keep a close eye on your cat's urination habits. If you notice symptoms like frequent urination, decreased urine output, pain or blood in the urine, seek veterinary care promptly.
