Susan Saks said the wallaby was last seen outside of Jaipore Indian Restaurant on Route 22 in Brewster a month ago.
"It's hard," Saks said. "We've been over to that restaurant so many many times. At least he's found a water source."
Saks said she thinks it will be easier to find him now that trees have lost their leaves and shrubs.
Previously, Indy was seen hopping across the street from North Salem Town Hall about six weeks ago.
"Hunters should be watching that they don't mistake him for a deer," Saks said. "His coloring is different and he doesn't stand up, but his face is deer like."
Saks said she is glad Indy has had his freedom, but she doesn't want him to get hurt.
Over the summer, Indy was seen by Four Winds Hospital, the Cross River Reservoir and the Waccabuc County Club in Lewisboro.
Saks has asked people to keep an eye out for Indy and to call her at 914-669-0006 or call animal control.
Saks said Indy loves to play tag and can recognize colors. He also loves the summer and enjoys lying out in the sun.
Aside from eating kangaroo dry food, Indy eats wheat thins, almonds, rice cakes, apples, lettuce, dry maple leaves and sweet potatoes.
Wallabys generally live three or four years in the wild, due to predators. Indy is 6.
The Saks family adopted Indy after their son rescued him from someone upstate who was bringing Indy around to schools.
