How Mold Affects Pets: What NYC Pet Owners Should Know

When thinking about the dangers of mold, most people focus on how it affects human health. But if you have pets at home, mold exposure can also pose serious risks to your furry companions—especially in New York City apartments, where ventilation and space are limited.

At Crown Mold Specialists, we’ve helped many NYC pet owners discover that their dog or cat’s health issues were linked to unseen mold in their living space. If you’re a pet parent, here’s what you need to know.

Why mold is harmful to pets

Just like humans, pets can inhale mold spores or come into contact with mold-contaminated surfaces. Since animals spend more time on the floor and near baseboards—where moisture and mold often collect—they may be more frequently exposed than you are.

Some molds produce mycotoxins, which are toxic to both humans and animals. Prolonged exposure can lead to allergic reactions, respiratory issues, and even organ damage in extreme cases.

Signs of mold exposure in pets

Because pets can’t tell us how they feel, it’s important to watch for symptoms that could be linked to mold exposure, such as:

  • Sneezing, coughing, or labored breathing

  • Watery or red eyes

  • Itchy skin or frequent scratching

  • Hair loss or skin rashes

  • Fatigue or changes in energy levels

  • Vomiting or loss of appetite (in severe cases)

If you notice these symptoms and they don’t improve with typical treatment—or they seem worse when your pet is indoors—it could be time to investigate for mold.

Where mold hides in pet-friendly homes

Even clean homes can harbor hidden mold, especially in moisture-prone areas like:

  • Around water bowls or litter boxes

  • Near leaky windows or under sinks

  • In basements or laundry areas

  • Behind furniture, especially near exterior walls

  • In HVAC systems or pet bedding that stays damp

How to protect your pets

1. Keep your home dry and well-ventilated
Use dehumidifiers and exhaust fans in kitchens, bathrooms, and basements to reduce indoor humidity. Ideal humidity is between 35–50%.

2. Wash pet bedding regularly
Make sure bedding, blankets, and toys are clean and dry. Avoid placing them in damp or poorly ventilated areas.

3. Clean spills and pet water areas promptly
Water bowls, food mats, and litter boxes can create moisture hotspots. Keep those areas clean and dry to prevent mold buildup.

4. Schedule a mold inspection if you suspect a problem
If you’ve seen visible mold, smelled musty odors, or noticed changes in your pet’s health, call a professional. We use tools to detect hidden mold and provide safe, effective remediation.
