Powerful Deodorizing FunctionThe garbage deodorizer adopts new deodorizing technology, which can remove more than 80% of the peculiar smell in the garbage. When the litter deodorizer is turned on, its sensor continuously monitors the usage of the litter box until the battery runs out, and automatically eliminates odors to ensure a fresh smell around the litter box. (The smell may not completely disappear on the first day of use, but after 2-3 days, you will feel a noticeable difference.) 100% Cat Friendly & Fragrance-freeThe litter box deodorizer releases deodorizing and dust-reducing substances (negative ions), and its emission is well within the standard range. Very friendly to you and pets. In addition, the deodorizer is equipped with a sensitive bio-sensing system, when the cat approaches the deodorizer, it will automatically turn off and automatically turn on when the cat leaves. Never worry about your meow again USB Rechargeable BatteryThe cat odor eliminator requires no expensive replacements or filters. Our litter box deodorizer is powered by low wattage. Uses USB charging and can work for up to 7 days on a single charge. Sturdy Snap DesignThe cat litter deodorant uses a heavy-duty cap with a snap cap with double-sided tape on the back to hang on any surface you like, so you can easily snap the deodorant by turning it into the lid, but the cat can't scratch it off.
