All Petco stores are cleaned and sanitized daily as part of our normal business operations. In light of COVID-19, we're increasing the frequency and extent of those cleanings and taking proactive steps to ensure all Petco locations (including stores and our distribution and support centers) have ample hygiene and sanitation supplies available.

Out of an abundance of caution, we’re making disposable gloves and masks available to all Petco partners, and requiring that all partners wear masks while working in our stores. Additionally, we have installed plexiglass barriers in Petco stores located in areas that are highly impacted by COVID-19, and are in the process of making this safety feature available in stores nationwide.

Each Petco store has several hand sanitizer dispenser stations in place at varying locations throughout the store, and we've instructed our store teams to ensure hand sanitizer is also available at all checkout locations, grooming salons and other high traffic areas of the store.

Using in-store signage, we're encouraging customers to help us keep our communities safe by maintaining at least six feet of distance from others, limiting the number of people per shopping trips when possible, and other recommended precautions.
