Mold and Pets: Signs to Watch for in Dogs and Cats
Dogs and cats experience a home differently than people do. They breathe closer to the floor, nap in closets and under beds, and press their noses into corners nobody else visits. In a humid place like South Florida, those are often the same spots where dampness and mold show up first. That does not mean every scratch or sneeze points to mold. It means your pet's habits are worth factoring in when something seems off.
Why pets may be more exposed
- They live low. Baseboards, carpet edges and the bottom of walls are where water from leaks tends to settle.
- They seek out quiet, enclosed spaces. Closets on exterior walls, laundry rooms and the space behind furniture have little air circulation.
- They groom themselves. Whatever lands on fur and paws can end up being swallowed.
- They stay home. Many pets spend nearly all of their time indoors, especially in Miami's summer heat.
Signs worth noting
The signs that owners most often associate with a damp or moldy environment are general ones, and each of them has many other possible causes, from fleas and food allergies to infections. Treat this list as a reason to pay attention, not as a diagnosis.
- Persistent scratching, chewing at paws or licking one area
- Red or irritated skin, or recurring ear trouble
- Sneezing, coughing or noisy breathing
- Runny nose or watery eyes
- Lower energy than usual
- Reduced appetite, vomiting or other digestive upset
Only a veterinarian can determine what is behind these signs. If your pet has trouble breathing, stops eating or seems suddenly unwell, contact a vet promptly rather than waiting to investigate the house.
A useful clue: does location matter?
One observation helps both your vet and your own search. Notice whether the signs change with place. Does your dog seem better after a weekend away or a stay at a boarding facility, and worse after a few days back home? Does your cat's sneezing pick up after sleeping in a particular closet? A pattern tied to a room or to the house as a whole is worth mentioning at the appointment and worth following up at home.
Pet-specific spots to check
Beyond the usual suspects such as under sinks and around the air handler, look at the places that belong to your animals:
- Bedding and crates. Lift the bed. A damp cushion on tile or a crate tray that traps moisture can grow mold underneath. Wash bedding regularly and dry it completely.
- Food storage. Dry food kept in a garage or on a humid patio can spoil. Store it in a sealed container indoors, and discard anything that smells musty or shows clumping or visible growth. Never feed it.
- Water and food bowls. Check the floor and baseboard behind them. Splashed water that sits day after day can damage wood flooring and drywall. A waterproof mat helps.
- Litter box areas. These often end up in bathrooms and laundry rooms, already the most humid rooms in the house. Make sure the space has ventilation.
- Favorite hiding places. Get down to pet level with a flashlight and look under beds, behind sofas and at the back of closets.
- Doors to the patio or yard. Wet paws and damp towels near a sliding door keep that area moist during rainy season.
- Aquariums and terrariums. They add moisture to a room. Look at the wall and cabinet behind them.
Cleaning safely around animals
If you find a small patch of growth on a hard surface, you can generally clean it yourself, with a few precautions. Move pets to another room and keep them out until the surface is fully dry and the room has aired. Follow label directions on any cleaning product, never mix bleach with ammonia or other cleaners, and rinse surfaces a pet might lick. Avoid masking a musty smell with strong fragrances or diffusers. Some essential oils are a concern for cats in particular, so ask your vet before using them, and remember that covering an odor hides the signal without addressing the cause.
Keeping the home drier
- Keep indoor relative humidity roughly between 30 and 50 percent, and below 60.
- Dry your dog thoroughly after baths, swims and walks in the rain.
- Run bathroom exhaust fans and keep the AC on a moderate setting when you travel.
- Fix leaks quickly. Wet materials can begin growing mold within 24 to 48 hours.
When to bring in a professional
Small surface spots are a cleaning task. Mold on drywall, in carpet, inside cabinets or around the AC system, and any growth that returns after cleaning, needs proper removal and a fix for the moisture behind it. During that work, pets should stay out of the affected area. To have the situation looked at, you can request an on-site remediation estimate at drymiami.com or call (954) 778-7999.
