Can Cats Be Allergic to Cat Litter?

Like humans, our feline friends can have (or later develop) allergies to certain things; cat litter is one of these things, unfortunately.

However, don't despair with thoughts of having to take your indoor-only cat outside ten times-a-day to do her business - not to mention the training involved in all that - when we've combed through the net and consulted with the experts to find how to solve this "itchy" situation.

How Do I Know If My Cat is Allergic to the Cat Litter?

Felines can be allergic to a number of things which may involve different factors. Food allergies can be to a specific ingredient like a meat-source or a grain additive, while other allergies can be caused by mold, certain fragrances, cigarette smoke, and more.

Allergies occur when the body is overly sensitive to something that has been ingested or inhaled. It then begins to perceive that matter as a threat and works hard to rid itself of the "invader."

While pinpointing the exact cause of your feline's reaction may be difficult, she will present you with some clear evidence of having an allergy. These symptoms include;

  • Sneezing
  • Coughing
  • Itchy skin and increased scratching
  • Itchy, runny eyes
  • Itchy ears with a tendency for ear infections
  • Swollen paws due to chewing on them
  • Vomiting
  • Diarrhea
  • Possible snoring due to an inflamed throat

Additionally, when a cat is reacting to the litter she may experience more coughing and sneezing when near or after using the box, facial swelling and acne. Some cats may even avoid using the litter box altogether.

The common compounds found in cat litter that may be causing your kitty problems are the bentonite, silica dust, or clay, plus the chemicals and fragrances used to make it more pleasant to us humans.

To tell if your cat is allergic to the litter you can try using a different brand to see if the symptoms clear up or have your veterinarian test for specific allergies.
