The intensity of the electromagnetic waves emitted by the Catlog Pendant is about 1/1000th that of the radio waves emitted by devices like cell phones. Currently, there is no scientific evidence that electromagnetic waves affect the brains of living organisms.
Furthermore, to ensure that the mechanical noise emitted from the device does not stress your cat's sensitive hearing, we have carefully selected parts for Catlog Pendant that produce minimal noise and conducted sound tests to confirm that it is essentially silent.
