The function of the pet water dispenser is to store water automatically, without the pet owner always changing the water for the pet. So it depends on whether you have time to change the water for your pet frequently. If you don't have time, consider buying one.
If you are a novice cat owner, you don't have to worry about buying a pet water dispenser. But if your cat likes to use a pet water dispenser and likes to drink flowing water, it is not impossible to buy one.

Let me tell you about my own situation, I have a little raccoon cat, I have not bought a pet water dispenser, I have placed water basins in several places in the house, and every morning before I go out, I will replace each basin with a clean water, and let it drink by itself during the day at home.

I will also often observe whether its urine or smell is normal, (careful friends can use the usage of cat litter to make a preliminary judgment), if it is found that the cat litter is used less, eliminate the urine in the cat litter Outside of the pot, I'll take steps like adding some water to her cat can or adding some water to her other food. Because canned cat food has an odor, it can attract cats to come and eat it.
My cat is pretty good, and they all drink water. I have a colleague whose cat is different. Every time he washes vegetables, his cat always comes over to join in the fun, and he even eats hot pot at home. Domestic cats also want to come and have a bite. Then my colleague thought that his cat bought a pet water dispenser. A few days ago, he thought it was quite novel. After playing with it like a toy for less than a week, the pet water dispenser was idle. Sometimes I really feel that cats are just like people, and they like the new and hate the old.

It is still necessary to let the cat analyze it in detail. First of all, whether it is an automatic water dispenser or a food bowl or food bowl, it is necessary to change the water diligently. Cats love to drink clean water, everyone should know this.

Secondly, it is necessary to observe more daily, the cat's water intake, use the food bowl to fill the water, and pay attention to the cat's water intake every day. The normal daily water intake for cats should be 40ml-60ml/kg (cat weight). If that's enough, and you're willing to change the water in the basin every 1-2 days, then there's no need to buy an automatic water dispenser.
If you don't drink enough water, you can first try to use a large bowl to fill the water, even if it's okay, it can be used as a footbath as long as it drinks enough water, it's not necessary if it wants to drink. If not, then buy an automatic water dispenser. Our family basically changes the water every 3-5 days. But the water dispenser should preferably have a relatively large opening. I bought Xiaopei before, but I still had blood in urine due to insufficient drinking water. It was 1000+ in the pet hospital, and I went to hang water every day, hurting people and cats. Later, I changed to a larger Universal Light, and the master drank a lot more water than before. So far so good.
Therefore, when the kitten first arrives home, we still need to spend more effort in the early stage to observe and guide the children's eating, drinking and behavior habits. I worked hard in the early stage and got to know the little guy in-depth, and I will save a lot of worry in the later stage.

We all know that the principle of pet water dispenser is to attract cats to drink water by simulating the natural flow of living water. So the question is, do all cats really like to drink running water?

The answer is definitely no. In fact, when I was working in a pet store, I also found that at least 1/3 of the cats did not care about the water dispenser.
For this type of cat, the water dispenser is just a toy, and they often make water in the house. Do you think that buying a water dispenser is not a guilt for yourself?

In other words, if your cat is currently eating mamaxiang, drinking water is normal, and the cat is not too dry, then there is no need to buy any additional water dispenser.
Just the kind of ordinary cat water basin is very useful. You can put a few more in different places. Remember to change the water for them often.

But if your cat doesn't like to drink clean water from the basin, often goes to the toilet to drink toilet water, or often goes to drink water from the tap, in this case, the water dispenser becomes a just need.

Because this type of cat really likes flowing water, buying an automatic water dispenser can significantly increase the cat's water intake.

At the same time, it should be reminded that if the cat has been drinking very little water, this problem must be taken seriously. Over a long period of time, constipation may occur in light cases, and blood in urine and stones may occur in serious cases.
According to a standard of the current pet hospital, the cost of treating stones is 4000+, which really makes the cat suffer with your wallet.
For novice cats, there is no need to buy a pet water dispenser immediately, because it may not be suitable for your cat, and it may not be able to increase the cat's water intake.

Usually, you can observe more of your cat's water drinking situation. If the drinking water is normal, then you don't need to buy a pet water dispenser at any time.

But if your cat doesn't like to drink the water in the bowl, and often goes to drink running water such as toilet water and faucet water, then I highly recommend buying a pet water dispenser, which can perfectly cater to the habits of cat owners.
