The online retailer started the partnership by donating £14,000 worth of products, which included a selection of dog bowls and silicon eating mats, in order for the charity to issue them as a pack with every dog and cat that is rehomed.
The packs will also include a £5 voucher or use on All Pets Solution website.
Earlier this month, Blue Cross announced it has reopened its animal hospital in Merton following a refurbishment.
The animal charity said that work was needed to update the reception area, dispensary and other public spaces within the hospital on Merton High Street.
The hospital now features a new operating theatre, as well as a new exotics kennel following the improvement work.
