5 easy ways to freshen your cat’s bad breath

If you’re lucky enough to have an affectionate cat who loves to cuddle, you’re a fortunate pet parent, indeed. That is until you get a whiff of your cat’s breath and realize just how grateful you are that humans brush their teeth multiple times a day. There’s tuna breath, and then there’s the fish steamroller that some cats have. Desperately need to know how to freshen cat breath? You’ve come to the right place!

What causes a cat’s bad breath?

Halitosis is the official name for the stench in your cat’s mouth. And while it’s tempting to blame your kitty’s diet, the source of the smell actually comes from the bacteria in their mouth. Don’t reach for an antibiotic as the answer to freshening your cat’s breath, though.

Not all of that bacteria is bad. Some of it’s needed to help break down your cat’s food. The bacteria go to work with the saliva, generating enzymes that start the digestive process. During the process, the compounds that get generated stink. The problem of kitty bad breath then gets worse when too much bacteria hangs around in the mouth.

Feline periodontal disease

As extra bacteria build up in your cat’s mouth, they form a film around the teeth known as plaque. If left untreated (we’ll get to how to solve that problem in a minute), plaque mixes with minerals in the saliva and hardens into tartar. As tartar thickens, the gums around the teeth recede, exposing the tooth root. Now there’s a pocket for food to get stuck in. Or, worse, with nothing to hold onto, the tooth falls out!

This process of damaged teeth and gums is known as periodontal disease. And 85% of cats have some form of periodontal disease by the time they’re 3 years old.

In addition to stinky breath, that extra bacteria can enter the bloodstream, leading to additional complications:

  • Cancer
  • Medical conditions of the:
    • GI tract
    • Heart
    • Liver
    • Kidneys
    • Pancreas (i.e., diabetes)
  • Poor appetite

So while you want to freshen your cat’s breath, you’ll also be taking steps to protect your cat’s overall health. (It’s a win-win!)

The best solutions for your cat’s bad breath

A professional cleaning

While it’s not an at-home step, making an appointment with your veterinarian for a professional dental cleaning tops the list. You’ll make your cat’s breath smell better, find any problems, and start with a clean canvas.

Your feline family member will get a full set of dental radiographs, a thorough oral exam (performed safely under anesthesia), and a polish and prophy. Then, you can take over with at-home care.

Brushing your cat’s teeth

Nothing works better for freshening a cat’s breath than regular teeth-brushing. Due to their small size, cats appreciate the use of finger brushes, which you wear on your index finger. You gently work the brush over their teeth. If you’ve never brushed your cat’s teeth before, you’ll need to take things slow, but cats can learn to tolerate the process.

When choosing your cat toothpaste and toothbrush, look for the Veterinary Oral Health Council (VOHC) seal of approval. VOHC only approves products guaranteed to slow the progress of plaque and tartar. It approves everything from toothpaste to treats.

Try the additive route

Not all cats appreciate toothpaste (and not every owner feels brave). Dental-water additives work as cat-breath fresheners. A few drops mixed into your cat’s water bowl will help with that tuna halitosis. Just keep in mind that water additives aren’t as effective as brushing, so you’ll need more frequent professional cleanings to make up the difference. Also, some cats hate the taste, and they’ll avoid drinking — not something you want.

Sneaking in dental treats

Cats love treats. Luckily for you, there are a host of dental treats on the market that help scrape that stinky plaque from your cat’s teeth. Your kitty gets a yummy snack, and you get to make your cat’s breath smell better.

Changing up your cat’s diet

The more wet food your cat eats, the more plaque will build up on their teeth. Dry food scrapes that plaque away — so long as they chew their food. (Cats don’t always chew their food. Cats with no teeth can still eat dry food without a problem.) If your vet gives you a heads-up about periodontal disease, you may need to rethink your kitty’s diet.

Whether you switch over to a dental diet or choose to use the diet as a treat (that works, too!), the larger kibble size encourages your cat to chew. The more plaque your cat scrapes off, the better chance you’ll make your cat’s breath smell better.

that cats love. The chicken flavor appeals to the pickiest appetite, and the kibble design attacks that pesky plaque and tartar. And, of course, you have the VOHC backing!

Stinky breath begone!

Finding ways to freshen your cat’s breath requires a little work. If you’re willing to put in the time to brush your cat’s teeth, though, you’ll find yourself rewarded. Your cat will get a shining, healthy smile, and you’ll get fresher kitty breath.

Happy brushing!

Why your cat is displaying this nasty behavior and what to do next

Cats have many reputations — for plotting your demise (probably not), destroying the holiday trees (fair), and night owl behavior (they can't help themselves). However, cats are also known for being good about using the correct facility. Their instinct to go in one gives kitties a point over dogs, which are generally more difficult to housebreak in cat lovers' books.

Yet, your cat is suddenly peeing on your clothes.
"Why does my cat pee on my clothes?" you ask. That's a good question, and the answer is critical to uncover. Here's why: Peeing outside of the litter box is a sign that something is up, especially if the cat usually uses one like a pro. So, what's up with kitty when they're peeing on your laundry? They're not trying to spite you, but instead, to send you a rather gross but important message. Here's what a cat is saying when they choose your favorite shirt over their box.

Why do cats’ eyes dilate? What your pet’s extra big peepers mean
Your cat might have big eyes because of darkness, excitement, or surprise

Sometimes you come home to a dark house, and through the pitch black of your living room, you spy two big round orbs. While it might look Halloweeny at first glance, this is actually just how your cat sees things. Cat's eyes seem to glow at night because they reflect light, a lot more than ours do in any case. Just as with other animals, you will see a kitty's eyes dilate, but what is your cat's pupils meaning? We'll walk through what your pet's eyes tell you about their feelings and physical state and when you need to step in and get your cat to a vet.
What does it mean when cats' pupils get big?

Big eyes on your cat could mean a few different things, some physical and some emotional. Rarely, you may find that your cat has a larger issue since occasionally dilated pupils can be medical in nature (we'll go into this more later). Fortunately, it generally doesn't have to do with any underlying condition and instead has everything to do with the current situation. Here are some reasons your cat might have extra large peepers.
They're hunting
Cats love to hunt and frequently do so at dawn and dusk — both inside your home and out of it. Your pet might not literally be hunting for prey, but they could still enjoy stalking their toys or food. When they're in hunting mode, you may see extra big eyeballs staring at the object of their interest.
It's dark outside
When you spend time in a dark room or outside at night, you'll almost certainly notice your own pupils get bigger. That's because our eyes open up to let in more light and allow us to see better. It's the same with your cat but theirs tend to stand out a bit more in part because of the prior mentioned reflectivity.
Something surprised them
If you've ever heard of eyes widening with surprise, this is what we're talking about. From a physical perspective, your globes are attempting to take in everything as quickly as possible, because this surprise could mean a bad thing. A wild cat could get startled by a predator for example and need that info to find a way to safety.
They feel anxious
You may discover that your cat has eyes that seem to dilate under certain conditions or more frequently than usual. It might mean they're experiencing some anxiety and want to destress. Ensure there is somewhere in your house where they feel secure and that the day-to-day routine suits their needs.
They're aggressive
Sometimes you might see your cat's eyes turn to slits before they get into a fight with another cat because narrowing the opening can help them protect their sensitive ocular region. On the other hand, having wide-open eyes gives your feline more information about their opponent. Pay attention to other signs of aggression, which will help you determine if this is causing the widening.
