Share Email Pinterest Linkedin Twitter Facebook

Mold can be found anywhere whether inside and outside, as its fungal matter thrives on warmth and moisture. Basements and dark, damp corners are obvious culprits, but pet beds can also harbor mold spores, as well as pet food if not correctly stored.

Quick Overview

01

Some cats are very sensitized to mold, so mold spores can set off an allergic reaction.

02

Even if cats are not allergic, ingesting or inhaling mold can still cause health problems, especially in the case of toxic black mold.

03

Cats can respond to mold exposure with skin symptoms such as itching and sore spots, respiratory symptoms such as sneezing or coughing, or gastrointestinal signs such as vomiting or diarrhea.

 

Mold can be harmful in a few ways for cats. Some cats are allergic to mold and have severe skin reactions if they come into contact with it. Mold can also be detrimental to our feline friends if inhaled or eaten. Some molds can be extremely toxic to cats and any exposure requires prompt veterinary treatment.

Common Symptoms Of Mold Allergies In Cats

Just like humans, cats can suffer from allergies. Cats can be allergic to many things, including parasites, certain foods, or things in their environment, such as pollen or dust.

One of these environmental allergens is mold. Unlike us humans, however, cat allergies usually present with skin problems, rather than the runny nose and sneezing that us people suffer from.

Typically, allergies in cats present with dermatological symptoms. Here are some signs that your cat may have allergies:

  • Excessive itching and scratching
  • Excessive licking or over-grooming
  • Hair loss (alopecia)
  • Red skin, including the paws
  • Sores on the skin
  • Runny nose or eyes

The symptoms of mold exposure are different. With mold exposure, a cat is not necessarily allergic to mold spores but they can still become unwell if mold is taken in through inhalation or ingestion. Some cats have a greater sensitization to mold than others.

When inhaled, mold can lead to breathing difficulties, sneezing, coughing, and nosebleeds. In severe cases, mold spores can cause damage to the lungs, leading to bleeding (small nasal hemorrhages, or more threatening pulmonary hemorrhage) which can lead to severe illness and long-term health problems.

If your cat eats mold (for example when playing with old toys or via their pet food), their reaction to mold exposure might be more gastric in nature. Vomiting, diarrhea, lethargy, and loss of appetite are common symptoms with ingestion of mold spores.

In rare cases, cats can become severely unwell if they are in contact with certain toxic black mold species, such as Stachybotrys chartarum. These deadly mold species release mycotoxins that can cause more concerning symptoms such as profuse vomiting, tremors, hemorrhages, and even seizures. Seek professional advice immediately from your veterinarian if your cat displays any of these signs.

Diagnosis Of Mold Allergies In Cats

If you suspect your cat is suffering from any allergy, whether from mold exposure or something else, schedule a checkup with your veterinarian.

Our pets can develop many different types of allergies. If your cat is unwell, seek help from veterinary professionals to discuss their symptoms. Your veterinarian will examine your cat thoroughly and will likely discuss their symptoms and their recent history, asking all about their pet food, their environment, and anything new that they may have been exposed to.

Your veterinarian might want to do some tests to rule out some other causes of illness. They might take skin samples to look for fleas or other parasites and to check for evidence of infection. If allergies are suspected, your veterinarian might recommend a skin test or a blood test that can look for sensitization of the body (allergies) to environmental factors such as dust and dander, which should also include mold allergies.
