Can an animal get through the insulation in the attic?

Yes, animals can often get through insulation in attics, especially if the insulation is damaged or improperly installed. Common pests like rodents, raccoons, and squirrels can chew through insulation material to create nests or find shelter. Additionally, gaps, holes, or weak spots in the attic's structure may allow animals to enter and disturb the insulation. It's important to seal any entry points and repair insulation to prevent wildlife intrusion.
