How It Works

Three steps to lasting freshness

Simple to use. Works with the litter you already have.

Before and after: an untreated litter box giving off odor versus one treated with Bio Safe PLM odor-control granules

STEP 1

Sprinkle

Sprinkle 4–5 teaspoons of Pet Litter Maxx into your existing litter every 2 weeks, or mix it in as you refill the litter box.

STEP 2

Adjust as needed

Add more as needed for larger litter boxes or stronger odors. Remove feces between applications. Extends litter life and keeps the bed dry.

STEP 3

That’s it

Enjoy a fresh, scent-free home. Odors are eliminated at the source, not masked by perfume.

Sprinkling Pet Litter Maxx granules from the shaker cap into a litter box

Store in a cool, dry area. Keep contents and packaging out of reach of children and pets. Wash hands with soap and water after cleaning the litter box.

Designed for every small member

Specifically formulated for pet litter boxes, and great for kittens learning to use one.
