There are a few things you can do to remove poop from leather car seats. The first is to use a plunger to suction onto the poop and pull. This will cause the poop to release from the seat and fall to the floor. The second is to use a vacuum cleaner with the hose attachment to suck out all of the poop. Finally, you can use a bucket or toilet paper tube to place all of the poop in one spot and then put the seat back in place.
