Can Mold Make Pets Sick in the Home?

Last updated October 25, 2026

The short answer

How Pets Are Exposed to Mold

Pets encounter mold in ways people often miss. They spend much of their time on floors and carpets, which can harbor mold growth after a water leak. They also sniff in corners and may lick damp surfaces, ingesting spores directly.

Birds are particularly sensitive to airborne spores due to their rapid respiratory systems. Small pets like rodents in cages near damp areas also face high exposure from their bedding and food, which can mold quickly in humid conditions.

Common Symptoms in Pets

Watch for respiratory signs like coughing, sneezing, wheezing, or labored breathing. Pets may also show nasal discharge or frequent scratching at their nose. These symptoms can be mistaken for seasonal allergies but may persist indoors.

Other signs include skin irritation, such as excessive licking, scratching, or developing hot spots. Digestive upset, including vomiting or loss of appetite, can occur if a pet ingests mold. Lethargy and a general lack of energy are also red flags.

  • Coughing, sneezing, or wheezing
  • Excessive scratching or licking of skin
  • Red or watery eyes
  • Vomiting or loss of appetite
  • Lethargy and reduced activity
  • Nasal discharge or pawing at the face

What to Do If You Suspect Mold

First, move your pet to a well-ventilated area away from the suspected mold. Do not let them back into the affected room. Schedule a visit with your veterinarian to discuss the symptoms and potential mold exposure.

Next, identify and address the moisture source in your home. Look for leaks, condensation, or past water damage. Visible mold often means a larger hidden problem. You need to stop the water to stop the mold from growing back.

Professional Mold and Moisture Control

For your family's and pet's safety, significant mold issues require a qualified mold assessment and remediation professional. The experts can safely contain and remove mold, preventing spore spread during cleanup. They follow strict protocols to protect the home's occupants.

Local water damage pros address the root cause: moisture. They find hidden leaks, dry out wet materials completely, and restore the area. This work helps prevent mold from returning, creating a healthier environment for everyone living in the home.

Preventing Mold to Protect Your Pets

Prevention starts with moisture control. Fix plumbing leaks promptly and ensure good ventilation in bathrooms and kitchens. Use dehumidifiers in basements or other damp areas, especially during humid seasons, to keep indoor humidity below 60 percent.

Inspect areas where pets spend time, like crates, bedding, and food bowls. Wash pet items regularly and ensure they are completely dry. Store pet food in airtight containers. Quick action after any water incident is the best defense against mold growth.

  • Fix plumbing leaks immediately
  • Use exhaust fans and dehumidifiers
  • Keep indoor humidity low
  • Wash pet bedding and toys often
  • Store dry food in sealed containers
  • Dry wet areas within 24 to 48 hours

Frequently asked questions

Are certain pets more vulnerable to mold?

Yes, birds, reptiles with respiratory infections, and small caged animals are highly vulnerable. Pets with pre-existing conditions like asthma or weakened immune systems are also at greater risk. Puppies, kittens, and senior pets may have less resilience.

Can I clean up mold myself with pets at home?

For small areas, you can clean with proper safety gear, but always remove pets from the home first. For larger patches, professional remediation is safer. Disturbing mold sends spores airborne, which pets can inhale.

Will my pet's health improve after mold removal?

Many symptoms improve once the mold source is removed and the air quality recovers. However, some pets may need ongoing veterinary care for respiratory or skin conditions triggered by the exposure. Always follow your vet's advice.
