This stuff does not normally operate in the presence of a cat .... !!!!
Our 9 year old twink adopts mice and shares croquettes with them.
(The last rat left in full health).
Nothing to expect from a hunter instinct nonexistent.
That said, he groans because of ultrasound!
Can not stand.
I prefer to leave them alone mice without the device suddenly I could not actually test.
Returned to its owner who has only his mouse and no cat :)
He says be very happy.
For us, in a few days it will not be a major concern, so leave these quiet rodents ^^
