How to Choose Sonic Cat Deterrents

Different environments call for different deterrent types. Outdoor models need weatherproofing and solar or battery options, while indoor devices may focus on discreet design and flexible power.

Power Source and Charging

Choose a power source that matches your setup. Solar is great for sunny gardens, while USB or AC is handy near outlets. Battery units are flexible but need regular checks.

Motion Sensor and Detection Range

A broader detection range is useful for large yards, while indoor use may need a shorter, more focused range. Adjustability can help tailor the device to your space.

Installation and Placement

Proper placement is key. Outdoor units often work best at animal head height and facing likely entry points. Indoors, position near problem areas like furniture or doorways.

Sound and Light Features

If you have pets or sensitive neighbors, consider the type and volume of alerts. Light features can boost effectiveness in low-light settings.

Durability and Weather Resistance

Outdoor deterrents must handle rain, sun, and temperature swings. Indoors, a compact, unobtrusive design is often preferred.
