Just sharing her new found toy with you!  From her perspective, it's
probably pretty funny watching you chase after it!  LOL

I have one in my kitchen but am not sure how good they are as i think i
have blocked the hole up that the little critters had got in through,
but still use it as a secondary measure!  I do know that they are only
meant to work in an open area. The sound waves bounce of everything and
do not go round or under things.

Not sure it would be much good to you if its your cat bringing them in,
as you may just drive the little creatures into otherparts of the house
if they are trapped in.

You would be wasting your money.

Pouring out of my Web browser came dozens of university publications
regarding the effectiveness of ultrasonic pest repellers:

“Ultrasonic pest repelling devices have repeatedly been shown to be
completely useless.” University of Florida

“Ultrasonic treatment devices (such as ultrasonic flea collars)
claimed to rid homes of pests are completely ineffective.” University
of North Dakota

“Ultrasonic devices do not meet advertisers claims for their
products.” University of Maryland

“With proper use of rodenticide baits, there are few situations where
the additional cost of ultrasonic devices is warranted.” University
of Saskatchewan

“Ultrasonic devices are frequently advertised as a non-toxic method
of cockroach control. However, extensive research has shown that
these devices neither kill nor repel cockroaches.” University of
Florida

With these testimonials before me, I could give Clark and his
listeners a definitive answer. You might wonder, though, why the
scientists came to their conclusions.

The reason ultrasonic devices don’t repel animals, even though they
can hear sounds we can’t, is that ultrasound does not pack much
energy. A sofa, a kitchen cabinet or a wall block almost all of the
sound waves. Just as you might quickly roll up your car window when
an ambulance howls past, a mouse or rat can duck behind a solid
object to hide from loud noise. When food, water and shelter are
present, a rodent can easily find different pathways that avoid the
ultrasonic sound waves. Insects don’t have ears but they can “feel”
sound. Even so, ultrasonic sound dissipates rapidly. A bug crawling
more than thirty feet away from a unit can’t even detect ultrasonic
noise.
