Peperomia plants will do best in bright, indirect sunlight. An east or west facing window sill is ideal for them at most times of the year. The only thing to watch for is to ensure they don't get excessive direct sunlight during the summer months, as this can cause leaf scorching.
This plant is non-toxic for cats and dogs and is a great air purifier.
