7 telltale signs your cat may be allergic to their litter (and what you can do to help)

If your cat is sneezing, coughing, or has a runny nose, you might think he’s sick. But those can also be symptoms of an allergy. Cats can be allergic to all sorts of different things. For some cats, the cause of their allergies is a central part of their lives: their cat litter. Those allergies get aggravated multiple times a day for a cat that’s allergic to litter. When you understand the signs of an allergy, you can recognize that your cat might have a problem and take the right steps to get to the bottom of it.

Why cat litter allergies occur

The ingredients in cat litter can cause allergies. Clumping litter generally contains silica, which produces silica dust, an irritant known to cause allergies in some humans and animals. Fragrances can also be potentially irritating. While clay litters tend to be the most bothersome, your cat can be allergic to any number of components in any litter.

How your cat uses the litter box contributes to these potential allergies. Cats dig in the box, bury their business, and scratch at the box sides and at the litter. All this activity can stir up dust and irritants, making the issue worse.

7 signs that could indicate a litter allergy

If you’re asking, “Is my cat allergic to his litter?” there are several signs to watch for. Here are seven common symptoms of a litter allergy.

  1. Sneezing
  2. Coughing
  3. Red, watery, itchy eyes
  4. Runny nose
  5. Wheezing
  6. Frequent scratching and itchy skin
  7. Facial swelling or swollen, inflamed ears

You might notice one or more of these symptoms, and their severity can vary. If your cat has an allergy and continues using the same type of litter, those problems can worsen.

Initially, you might notice symptoms only when your cat is in or near the box. However, dust from the litter can get stuck on your cat’s paws, and your cat can track it through the house and into his bed. If this happens, then your cat might experience those symptoms no matter where in the house he happens to be.

Your cat will become uncomfortable, and if he realizes that the symptoms are worse when he uses the litter box, he may start avoiding the box.

What to do if your cat has a litter allergy

  • Change the type of litter. One of the first steps necessary to address a cat litter allergy is to change the type of litter you use. Look for a litter that’s free of the ingredients found in your cat’s current litter. To accomplish this, you’ll probably need to change the litter type entirely. For example, if you’re using clay litter, switching to pine or corn litter can help.
  • Thoroughly clean the litter box. Before you use the new litter, thoroughly clean out your cat’s litter box. Give it a good scrubbing to ensure you remove all the dust from the previous litter. You’ll also need to clean all the areas of your house where the litter dust could have been tracked. This means cleaning your floors, your carpets, your cat’s bed, his cat tree, and any other areas your cat spends time.
  • Clean the box frequently. Change your cat’s litter over to the new litter and then prioritize frequent cleaning. Vacuuming and sweeping up often can help reduce the allergens in your home. Monitor your cat for signs of improvement to see if changing the litter helped.

Remember that your cat may be allergic to multiple things in your home, and he can also be allergic to different ingredients in different types of litter. Removing and changing his litter could improve his allergies, but it may not eliminate them altogether. Your vet can explore other potential allergens that are bothering your cat and might recommend a food-elimination diet or even allergy testing to pinpoint what he is allergic to. Managing your cat’s allergies can take some hard work and persistence, but it can pay off with a healthier, happier cat.

Why do cats meow excessively? 6 possible causes – and solutions that can help you both
Find out why your cat is meowing so much (and what to do about it)

Cats meow (and don't meow!) for a number of reasons. It all starts when they’re kittens — they meow to their mothers when they’re cold, hungry, or scared. As they get older, little felines learn different ways to vocalize and interact with other cats, usually by yowling or hissing. But meowing is an adult cat’s way to communicate with people. It's nice to have a little chat with your tiny tiger, though constant meowing can be really unpleasant. If you regularly ask yourself, "Why do cats meow so much?" you're in the right place.

Why do cats meow to their humans?
Good news first: Many of the meows you hear indicate a positive feeling. This means, your cat gets happy and just has to express herself in her native tongue. However, sometimes, vocalizations can reveal the total opposite and require you to take care of her. Occasionally, excessive talking from a feline says that she's not OK and needs some human intervention. As with learning a new language, you should pay careful attention to the timing, intonation, and context of the articulation. Basically, trust your pet. If she's really in pain, you'll know from the noises she makes and should take her to the vet as soon as possible.

There are many reasons why your feline fur baby should remain exclusively indoors, but it's all the more important to keep your cat inside during the winter months. A blanket of snow may look stunning, but it makes it difficult for outdoor kitties to find their way home.
