The answer to 'why is my carpet pet stains' is that pet accidents and stains are a common issue for many homeowners. Pets can leave behind urine, feces, or other bodily fluids that soak into the carpet fibers and padding, creating stubborn stains and odors. Common causes include improper house training, anxiety, or medical issues in the pet.
The symptoms of pet stains on carpets include visible discoloration, a lingering odor, and potential bacterial growth or mold if the stain is not properly cleaned. To address pet stains, it's important to act quickly and use the right cleaning techniques. For fresh stains, you can try blotting with paper towels, using an enzymatic cleaner, or applying a baking soda and vinegar solution. For set-in stains, you may need to rent a carpet cleaning machine or call in a professional carpet cleaning service.
