Here's why:
* Varnish contains volatile organic compounds (VOCs): These chemicals evaporate into the air and can be toxic to animals, especially smaller ones.
* Respiratory issues: VOCs can irritate the respiratory system, causing coughing, sneezing, difficulty breathing, and even pneumonia in pets.
* Eye and skin irritation: Some varnishes contain ingredients that can irritate eyes and skin, leading to redness, itching, and discomfort.
* Ingestion: If a pet ingests varnish, it can cause serious health problems, including gastrointestinal upset, vomiting, diarrhea, and even liver or kidney damage.
What to do:
* Ventilate the area: When applying varnish, ensure the area is well-ventilated to minimize the concentration of VOCs in the air.
* Keep pets away: Keep your pets away from the area where varnish is being used and for several days afterward, until the smell dissipates.
* Store varnish safely: Keep varnish securely stored in a location that is inaccessible to pets.
* Monitor your pet: Watch for any signs of illness in your pet after exposure to varnish, such as coughing, sneezing, lethargy, or loss of appetite. If you notice any symptoms, consult your veterinarian immediately.
In general, it's best to avoid using varnish around small pets whenever possible. If you must use it, take extra precautions to ensure their safety.
