    It beats me why people want cats as pets, when they spend most of their time on other peoples property...

    Cats don’t have owners, they have staff!

    That tends to be the excuse cat owners give as to why they have none or little control over their pet.
    The cat controls them, they don't control the cat.

    Catnip or cat food laced with warfarin? :confused:

    I'm not a cat lover but I certainly wouldn't go that far.

    Neither would I. It would be illegal.
    You could perhaps use catnip as an under planting for lilies, purely for decorative purposes of course.

    Not everyone can hear it. Only the special people can hear them ;)

    ps - Dog whistles are also annoying!

    I have always been of the belief that ultrasonic implies a frequency above 20KHz. For an adult to be able to hear something above that frequency is exceedingly rare. Last time I tried I could, just, hear 16KHz.

    Shortly after I started work (in a research lab) and aged 24 I could hear up to 22kHz on the lab's oscillator and speaker. Now, it's very different - I can no longer hear the kitchen timer unless it's on the table beside me. I've been suffering from otosclerosis since around 1995 - possibly earlier.

    I never tried that when I had access to such equipment but I do have a signal generator app on my phone which is useful for testing audio systems,

    Mine are kept indoors so they cannot annoy neighbours by cra**ing in their gardens or threaten any wildlife bigger than a house fly

    I think my hearing level is just below the wife’s voice frequency of which there appears to be no upper limit :)
