Question: "For scaring away dogs and cats, what stationary device is the most effective? Thanks!"
Answer: The answer is dependent upon whether you want to keep the cat or dog off a particular place like a table or a car or whether your purpose is to keep the animal out of your yard.
Ultrasonic Area Repel Devices for Cats Only:
- The CatStop by Contech. An ultrasonic cat repeller that is motion activated and uses a high decibel alarm that startles the cats to leave while not disturbing the peace. This unit operates for about nine months on one standard 9 volt battery. (Battery life estimate is based upon 4900 activations over 245 days at an average of 20 per day.) The CatStop protects about 330 square feet (20 feet or 6m in front of the unit in an 80 degree arc). There are no controls or adjustments. Install the battery. Position it in your yard. Turn it on. The ultrasonic alarm is from 21-25 kHz, levels rarely heard by animals other than cats.
Ultrasonic Area Repel Devices for Dogs and Cats:
- The Koolatron Dog and Cat Repeller with AC Adapter and the Lentek Koolatron Dog and Cat Repeller, Battery Only. These are identical except for the AC adapter. use PIR (passive infra red) motion sensors, are powered by two 9V batteries (not included) and battery life is approximately 2000 sound releases. Mount no greater than 3 feet as close as possible to the area to be protected. 85 feet range at a 70 degree arc. Waterproof to IPX4 standard. Advanced ultrasonic sirens: Ultrasonic sound: 80 to 115dB; Frequency sweep: 18 kHz to 24 kHz.
- The Bird-X Yardgard Outdoor Animal Repeller is the most powerful unit (and most expensive) motion sensor activated unit that we sell. The coverage: 4,000 sq. ft. (278.7 sq. meters) , Frequency range: 15,000 - 25,000 Hz (adjustable) Sound pressure: 90 dB at 3 feet . Electricity costs: Less than $0.25 per month or uses 4 "C" cells (not included). Working current: <200>
- The Animal Away Pro. Power supply: 9V (Two 9V akaline batteries, not included)Power: Standby current: 0.16mA . Warm up time: 30 seconds. Frequency range: 18,000 Hz to 24,000 Hz. Protection coverage: Fan shaped area of 70 degrees, distance up to 40 feet. Material of plastic housing: ABS plastic. Again motion sensor activated.
Protect a tabletop or car in a garage from dogs or cats:
- Scat Mats. These are clear plastic static mats that come in large and medium sizes and strips run on either 9 volt batteries or an AC adapter. To extend coverage, you can buy extension mats. The animal/animals don't like the harmless static electricity generated and stay off.
- The Contech Mini Scarecrow is motion sensor activated and uses a warning sound followed by a puff of compressed air to scare an animal off a surface. Once your pet responds to the warning sound, switch to "sound only" mode and conserve compressed air. The motion sensor and spray are separately adjustable to allow precise positioning. Keeps dogs and cats from scratching furniture and drapes, jumping on counters, window sills, tables; entering a room, etc.
Please take a few minutes to examine the details on one or more units before you make your choice. We also sell a standard Animal Away unit that is less expensive and less powerful. The advantage of this unit is you can use it inside or buy several units to surround an area.
Hope this helps. We thank you for your question.
