Woof, woof! Pet entrepreneur Allen Simon invented the so-called Wee-Wee Pad.
Now he’s slashed close to $13 million off his own palatial pad, which is on the market for $27 million — down from its original asking price of $39.9 million in 2019. The sixth-floor Central Park spread is at 838 Fifth Ave. and 65th Street.
It’s in a former 11-story office building that dates to 1950 and was converted to just nine condo units by developer Harry Macklowe in 2000.
Back then, Simon and his wife Cynthia bought the full-floor, five-bedroom, five-bathroom residence for $10.8 million in 2000.
At the time it was just raw space. Simon got his start working in a Brooklyn pet store, then launched Four Paws in 1970.
Today, he’s CEO of PetProducts.com and has manufactured and invented more than 200 pet products, including the Wee-Wee Pad and the Allen pooper scooper.
At 5,427 square feet, the sprawling, 10-room residence opens to a private elevator landing and a 45-foot corner room overlooking Central Park, along with a living room fronting Fifth Avenue with lots of windows, beamed ceilings, hardwood floors and a fireplace.


There’s also a formal dining room with a fireplace, coffered ceilings, hardwood floors, a crystal chandelier and built-in cabinets. A modern eat-in chef’s kitchen leads to a central gallery and a wood-paneled library with a gold leaf-painted ceiling and a built-in wet bar.
The bedroom wing includes a main suite with a light-filled office, bedroom with Juliet balconies, two full-size dressing rooms, a fireplace and two marble bathrooms.


The sale also includes a large private staff room with a full bath and kitchenette on the lobby level, along with two storage bins off the lobby and two wine cellars. Building amenities include a gym.
The lobby, built by Jack Beyer, of Beyer Blinder Belle, was designed with a sitting area, antique furnishings and a fireplace. The listing broker is Douglas Elliman’s CB Whyte.
