In short: tap water does not harm cats. In Germany, the water from the tap can generally be used as drinking water for humans and animals with a clear conscience. Only good water quality has to be guaranteed to save the tigers from indigestion, diarrhea and vomiting.
Tap water for cats: a question of where you live
In general, the water quality depends on where you live. Mostly safe in Germany, the water is inedible in other parts of the world. If the tap water in your area is very dirty, chalky or enriched with many additives such as fluoride, it is worthwhile to use products such as mineral water.
If this is not the case, the normal tap water is sufficient. As a rule of thumb: If you can tolerate the water from the tap, it can also be enjoyed by your cat. If in doubt, you should consult your responsible water company.
How often should you change the drinking water?
In order to maintain the high quality permanently, the drinking water should be replaced with fresh tap water several times a day. In summer, when the heat is high, the water spoils faster - then it is advisable to replace it about every three hours.
Ideally, choose a low-maintenance container made of stainless steel or ceramic as the drinking bowl. Place the bowl a few meters away from the feed bowl. Also clean the drinking and feeding bowl regularly and thoroughly. Make sure that the drinking bowl is always full so that your fur nose always has fresh water at its disposal.
Cats and water: top or flop?
Encourage cats to drink
Cats are often lazier to drink than other pets. Even if cats don't sweat, they need the water badly. It helps them control their body temperature. Even a fluid loss of ten to 15 percent throughout the day can harm the velvet paws and, in the worst case, even lead to the death of the animal.
Therefore, it is the responsibility of the cat owner to get his fur nose to drink. A stable indoor fountain can be useful. A gently splashing water feature magically attracts cats and often tempts them to taste a sip or two. Ideally, you should also distribute a few water bowls all over the apartment.
Tips for descaling cat fountains
Nevertheless, the water quality must also be right for the cat fountain. Therefore, as with the bowl, the following applies: Exchange water and regular cleaning is a must. Tap water must of course be used so that the water from the well is compatible with the house tigers. However, the pipes inside the water feature can calcify over time if you do not use a decalcifier from time to time. But be careful: Make absolutely sure that it is a biological, non-toxic agent and rinse the fountain thoroughly after use.
