Monitor Pet Urine Marking & Urination in Your Home


Dogs and cats are hypersensitive to smells and live in a scent-centered world. They instinctively spray urine to mark their territory. The SprayAlert® Alarm (US Patent 6,860,239) instantly emits a startling sound when sprayed by urine.

Place the urine sensor in spots where the pet marks or urinates. The alarm sound can interrupt the marking, limit damage, and act as a future deterrent. For dogs, redirect to the correct area and reward for good behavior. Effective as a dog or cat urine/pee alarm to notify you asap for quick cleanup.


Immediate feedback for a dog is essential to change behavior.  Avoid aversive training or punishment. Reward-based training is more effective. The unit has two volume settings, use the quieter one if concerned about stressing the pet.
