Stopping Cats from Using Houseplants as Litter Boxes

Effective Soil-Top Deterrents

Citrus peels (orange/lemon) – scent repellent.
Pine cones – texture aversion.
Aluminum foil balls – movement and sound.
River rocks or decorative stones – prevent digging.

Why They Work

Cats prefer loose, diggable substrate. Covering soil with immovable or unpleasant materials redirects them to the litter box. All methods are plant-safe.
