"If you walked by and read their message, you wouldn't know it had anything to do with PETA," said Don Cowan, PETCO's director of communications.
Exactly. No one would have ever noticed that. I bet if you went through all those bricks, there would be multiple "secret messages" ... simply at random.

PETA does the dumbest things, I swear ... this is a case in point. They consistently miss their target audience .... like baseball fans are going to spend their time at the stadium searching for hidden messages in bricks, then saying, "Oh, gee! I paid for season tickets to see baseball, but I guess I'll just go home and boycott a pet store." Puhleese.
