Coles has abandoned its $4 billion bid to acquire Greencross, the owner of Petbarn and City Farmer, citing concerns over the valuation.The decision comes after shareholder pressure to preserve capital, with the proposed price of $3.9 billion deemed excessively high.This follows Woolworths' $586 million purchase of Petstock four years ago, which was valued at $1 billion at the time.Greencross now generates $2 billion in annual revenue and $400 million in profit before interest, tax, and depreciation.

Critics argue that the pet industry's growth potential is overstated, and supermarkets should focus on core challenges like integrating technology into supply chains and competing with Amazon.

Past attempts by Woolworths to expand into non-core areas like hardware and pubs have ended in costly failures, highlighting the risks of straying from core competencies.Investors remain skeptical of diverting capital to pet-related ventures, preferring dividends over pet-related investments.
