Every spring, Maryland households shake off the winter and get to work. Windows get thrown open, closets get emptied, and products you forgot you owned get pulled out from under the sink. It feels like a fresh start. But for your cat, spring cleaning season introduces a wave of hazards that most owners never think twice about.
Cats are curious by nature and low to the ground by habit. They walk across freshly mopped floors, investigate open cleaning product bottles, groom chemical residue off their paws, and nap in closets where fumes can concentrate.
What’s routine for you can be genuinely dangerous for them. At Catonsville Cat Clinic, we see a predictable uptick in accidental exposures every spring, and the vast majority are preventable with a little awareness.
Here’s a guide to the household products that pose the greatest risks to cats, what signs to watch for, and what to do if your cat is exposed.
All-Purpose and Disinfectant Cleaners
Products containing bleach, ammonia, or quaternary ammonium compounds (found in many popular disinfectant sprays and wipes) are among the most common sources of feline chemical exposure. These ingredients are effective at killing germs, but they don’t discriminate — they also irritate cats’ mucous membranes, airways, and paws.
The problem isn’t just direct contact. A cat walking across a freshly sprayed countertop or floor will absorb residue through their paw pads, then ingest it while grooming. The effects can range from mild drooling and pawing at the mouth to vomiting, difficulty breathing, or chemical burns on paws and mouth tissue.
What you can do:
- Keep cats out of any room you’re cleaning until surfaces have fully dried — not just wiped down, but air-dried
- Rinse mopped floors with plain water after using any chemical cleaner
- Store all spray bottles and wipes in closed cabinets, not on the floor or countertops
Toilet Bowl and Drain Cleaners
These are among the most caustic products found in any home. Toilet bowl cleaners often contain hydrochloric acid or sodium bisulfate.
Drain cleaners commonly use sodium hydroxide (lye), which can cause severe chemical burns to the mouth, esophagus, and stomach on contact. Both categories become especially risky in spring when bathrooms get a deep clean and products are out longer than usual.
Cats that drink from toilets where in-tank or in-bowl cleaning tablets have been used are regularly exposed to low levels of these chemicals. Over time, repeated ingestion can cause serious damage. Cats who investigate and sniff open drain cleaner containers can suffer respiratory irritation from fumes alone.
What you can do:
- Keep toilet lids down, especially if you use in-bowl or in-tank cleaning tablets
- Never leave open containers of drain or toilet cleaner unattended
- Close the bathroom door entirely when using these products
Laundry Products, Including Pods
Laundry detergents, fabric softeners, and dryer sheets all contain ingredients that are irritating or toxic to cats. But concentrated detergent pods deserve special attention. Their colorful, gel-filled design can attract a curious cat, and a single pod contains a highly concentrated amount of detergent — far more than liquid detergent in the same space.
Biting into a pod causes the concentrated detergent to squirt into the mouth and airways, which can cause vomiting, drooling, lethargy, and in serious cases, respiratory distress.
Dryer sheets are another overlooked hazard. Cats are attracted to their scent and may chew or lick used ones left on countertops or pulled from a warm dryer. The cationic compounds in dryer sheets can cause drooling, vomiting, and oral ulcers.
What you can do:
- Store pods in their original sealed container in a cabinet your cat cannot access
- Discard used dryer sheets immediately and keep the laundry room door closed
- Avoid leaving detergent within reach on top of the washer or dryer
Essential Oil Diffusers
Essential oil diffusers have become a fixture in many Maryland homes, and they’re one of the hazards we want to emphasize most. Cats lack a liver enzyme called glucuronyl transferase, which is required to metabolize many compounds found in essential oils. This makes them uniquely vulnerable to essential oil toxicity compared to dogs and humans.
Oils that are particularly toxic to cats include tea tree, eucalyptus, peppermint, clove, cinnamon, citrus, and pine. Even passive diffusion into the air can cause respiratory irritation, drooling, vomiting, unsteadiness, and in higher exposures, liver damage. Cats who walk through diffuser mist or rest near an active diffuser absorb oils through their skin and lungs, then ingest additional amounts while grooming.
Spring cleaning season often means running diffusers more — to freshen up rooms after being closed all winter.
If you use a diffuser in your home, this is worth taking seriously.
What you can do:
- Run diffusers only in rooms your cat cannot enter, with good ventilation
- Never apply essential oils directly to your cat’s fur or skin
- Store all essential oils in sealed containers out of reach
- Consult us before using any essential oil products in a home with cats
Air Fresheners and Plug-Ins
Aerosol air fresheners, plug-in diffusers, and scented sprays are popular spring staples, but many contain volatile organic compounds (VOCs), formaldehyde, and other chemical ingredients that accumulate in indoor air. Cats spend far more time indoors than most people, breathe closer to the floor where particles settle, and groom themselves constantly — making them more vulnerable to airborne irritants than humans in the same space.
Chronic low-level exposure to air fresheners has been associated with respiratory irritation and upper airway inflammation in cats. If you’ve noticed your cat sneezing more frequently, coughing, or showing watery eyes around the time you’ve been freshening your home, the products you’re using may be the reason.
What you can do:
- Open windows for natural ventilation instead of masking odors with sprays
- Avoid spraying aerosols directly in areas where your cat sleeps, eats, or spends most of their time
- Look for fragrance-free or genuinely non-toxic cleaning products — not just “natural” ones, which can still contain harmful plant compounds
The Hidden Risk: Moving Stuff Around
Beyond the products themselves, spring cleaning creates a second, less obvious hazard: disruption. When you move furniture, pull out storage boxes, and open up spaces that have been closed all winter, you create new areas for your cat to explore. Garage shelves get reorganized, putting automotive fluids and pest control products within reach. Closets get emptied, leaving cleaning supply bags accessible on the floor. Storage rooms get opened that have been shut for months.
Cats are fast, opportunistic explorers. A box of mouse bait moved during a garage clean-out, a forgotten bottle of paint thinner left on the floor, or even mothballs unearthed from a stored box of winter clothes can become hazards in seconds. Mothballs in particular deserve mention — they contain either naphthalene or paradichlorobenzene, both of which are toxic to cats and can cause vomiting, lethargy, anemia, and liver damage.
What you can do:
- Keep your cat in a separate room while reorganizing storage areas
- Do a sweep of any area your cat can access after cleaning to make sure nothing hazardous was left out
- Replace mothballs with cedar blocks, which are safer (though still best kept away from cats)
Signs Your Cat Has Been Exposed to a Toxic Product
Cats are expert at hiding discomfort, so knowing what to watch for after cleaning day is important.
Contact us or an emergency veterinary clinic right away if you notice any of the following:
- Drooling excessively or pawing at the mouth
- Vomiting, especially repeatedly
- Coughing, wheezing, or labored breathing
- Red, watery, or squinting eyes
- Sudden lethargy or unsteadiness
- Redness, irritation, or burns on paws or around the mouth
- Twitching, tremors, or seizures
If you saw your cat come into contact with a specific product, try to bring the packaging or take a photo of the label. The ingredients list will help us or poison control determine the appropriate response quickly. Do not try to make your cat vomit unless instructed by a veterinarian — with caustic products, this can cause additional damage on the way back up.
The ASPCA Animal Poison Control Center is available 24/7 at 1-888-426-4435 for guidance while you’re en route to care.

If your cat has been exposed to a cleaning product, essential oil, or other household chemical — or if you’re not sure and they don’t seem like themselves after cleaning day — don’t wait. Cats can deteriorate quickly with certain chemical exposures, and early treatment makes a significant difference.
