Chlorhexidine Gluconate

When purchasing a cat water additive, it should be cautioned as potentially harmful chemicals might be a part of the concoction. One such chemical is chlorhexidine Gluconate which can potentially increase the formation of calculus.

Further, it can also lead to the inflammation of your cat’s salivary glands along with inflammation in the gums and mouth.

Another well-known chemical added to cat water additives is Xylitol. It isn’t just harmful to your pets but also potentially fatal. Therefore, it is wise to check the list of ingredients in your cat water additive to ensure it doesn’t pack in Xylitol in any form.

How can you use a cat water additive?

Before you start including a cat water additive in your pet’s bowl, make sure you consult with your local veterinarian. Get their advice on the brand you plan to select for your cat.

It is especially necessary for cats that have any pre-existing health issues that require medications.

When using water additives, make sure you follow all the given instructions in the packaging. Generally, the instructions are very simple and involve dispensing a measured proportion of additives in specified dosages.

Things to Look for in Cat Water Additives

Shopping for the right cat water additives can be a difficult choice. You need to check for certain features and ingredients to ensure it is completely safe for your pet.

Here are some factors you need to bring into consideration:

1. Antibacterial Properties

Bacteria are a primary culprit when talking about dental and stomach issues caused due to infected water. When ignored, it can lead to teeth burrowing & cause cavities. Moreover, they can also induce gingivitis along with gum infection. Therefore, look for cat water additives with natural & anti-inflammatory ingredients such as ginger, cloves, aloe vera, green tea extracts, & cinnamon.

If you don’t like artificial ingredients, make sure you stay away from citric acid or glycerin additives.

2. Breath-Refreshing Agents

Although the anti-bacterial agents take care of your pet’s oral health, it is a long-term process. For pet parents seeking immediate effect, you can look for breath-refreshing agents such as peppermint or spearmint.

3. Safety Feature

When using cat water additives with chemical ingredients, it is important to consider your pet’s safety. While most chemicals used in such additives aren’t harmful, some might lead to health issues for your cat in the long run.

As mentioned earlier, your cat needs to stay away from sweeteners such as Xylitol or any ingredient with alcohol. Instead, opt for additives that have safer ingredients for pets.

4. Taste

Cats are very wary about the water they drink. Any weird taste can deter them from drinking water at all. Therefore, cat water additives are generally used to make the water taste better and eliminate any foul smell that they cannot tolerate.

Additives with strong flavors can be a big turnoff for cats. So, make sure you choose something mild that isn’t too overpowering.

5. Consider the Cat’s Gut Health

Always choose a cat water additive that is light on your cat’s stomach. Several ingredients in cat water additives might worsen your cat’s digestive health if they already have a problem. Instead, get something that isn’t too overbearing in terms of formulation.

Now that you know the basics of picking the right cat water additive, here is a list of the top 10 options for you to select.
