Any tricks to keep cats away from speaker grills?

Kelly, since WHEN do we NOT think about going to EXTREMES around here, eh?
We just use a water bottle and a lot of patience.....

Pet Peeve Ultrasonic Trainer
#SI478GRY
$39.95

Keep pets off furniture — even when you're not at home!

Record a command to your pet ("Off the chair, Rover!") up to 10 seconds long.
If your pet jumps on furniture, a motion/vibration sensor is triggered.
Sensor causes playback of your command and a safe ultrasonic alert.
Features adjustable sensor sensitivity and ultrasonic alert-only option.

Of course, this is assuming that your cats actually LISTEN to you :-)

The water bottle works wonders. You just have to be consistent and get them each time they go near it.

Best of luck,
Angela
