Miller moths in homes often lead to curious cats engaging their natural predatory instincts. These moths, typically gray or light brown with a wingspan of 1.5 to 2 inches, are the adult stage of the army cutworm and are common household nuisances during their migrations. Cats are inherently drawn to the erratic movements of insects, making moths an enticing target for their hunting and play behaviors. This interaction is a natural expression of a cat’s predatory nature, providing both mental stimulation and physical activity.
Are Miller Moths Safe for Cats?
Generally, miller moths are considered non-toxic to cats, meaning consuming them is not typically harmful. However, some cats might experience mild digestive upset, such as nausea, vomiting, or diarrhea, especially if they eat more than a few moths. These reactions are usually temporary and do not indicate poisoning. While some varieties of moths are reputed to have toxic powder on their wings, this is not typically the case for common miller moths, and issues are rare.
Potential Concerns Beyond Toxicity
While miller moths are generally not toxic, other concerns can arise if a cat eats them. One potential issue is mild digestive upset caused by the indigestible chitin exoskeletons of the moths. Although rare, some cats might experience an allergic reaction to insect ingestion, with symptoms like skin pustules, swelling around the eyes, or labored breathing.
A more significant concern is the possibility of pesticide exposure. If moths have come into contact with insecticides, ingesting them could transfer these harmful chemicals to your cat, posing a serious health risk. While small moths present a low choking risk, larger moths could potentially become lodged in a cat’s throat, leading to coughing or difficulty breathing.
What to Do If Your Cat Eats Moths
If your cat eats moths, observe them for unusual symptoms like vomiting, diarrhea, lethargy, excessive drooling, or changes in behavior. If your cat exhibits persistent digestive distress, difficulty breathing, seizures, or any severe symptoms, contact a veterinarian immediately. Prompt veterinary attention is crucial, especially if pesticide exposure is suspected, as insecticide poisoning can cause neurological symptoms, respiratory distress, and can be fatal. To reduce moth encounters, consider installing screens on windows, keeping outdoor lights off at night to deter moths, and providing engaging toys to redirect your cat’s hunting instincts. Avoid using mothballs, as they contain concentrated pesticides that are highly toxic to cats.
