Mr. Rogers’ puppet Henrietta Pussycat might say about Pet Club, “Meow, meow, meow — cheap.” It’s been called the Costco of pet stores because of its big-box size and low, low prices. Here are just a few recent price comparisons between Pet Club and another chain, Pet Food Express: 20-pound bag of Science Diet cat food ($20.99 at Pet Club, $35.99 at PFE); 20-pound bag of Iams cat food ($22.99 at Pet Club, $32.99 at PFE); a 40-pound bag of Iams dog food (on sale for $21.99 at Pet Club, $36.99 at PFE). If the bargains aren’t enough, you can download coupons from the Web site. Also impressive is the amazing selection for all different kinds of animals. The store sells food and accessories not just for dogs and cats, but also rats, hamsters, guinea pigs, and rabbits. In the Emeryville store you can hear the chirping of crickets sold twenty for a buck as reptile food. If you’re not into animals with legs, there are also tropical fish and aquariums to consider. Oh, and be sure to bring cash or an ATM card, because Pet Club doesn’t take credit cards.
