“To the editor, Thank you for your cover photo of Bruce Ratner that appeared in the same issue as a full-page ad for his Barclays Center (“Dig it,” March 12). I have elderly cats who cannot always make it into the actual litter box, and I have to line the floor with paper for these times. The large ad works well for the cat who is most ill, since it’s a full page to hit. My other cat prefers target practice, however, and your front page picture of Ratner has successfully been targeted many times in both liquid and solid form, if you catch my drift. I have long been a fan of The Brooklyn Paper, and although Atlantic Yards coverage has been scant of late, this issue makes up for it. The cats have not had as much fun since we had all those Bloomberg ads showing up in the mail last fall. Steve de Sève, Brooklyn Heights”
