Why No Houseplant Can Replace a Litter Box Deodorizer in a Dark Bathroom

A reader wanted a low‑light plant for a windowless bathroom near a cat litter box to absorb odors, possibly moving it to light 1–2 days/week.

Plants Need Consistent Light

All houseplants are tropical and require a location bright enough to cast a shadow during daylight hours. One or two days of light per week is insufficient.

Scented Herbs Aren’t Strong Enough

Herbs need bright light and don’t mask litter odor effectively.

Real Solution

Frequent litter box cleaning by the owner + a passive air deodorizer (e.g., Air Wick) in the room.
