We have a deaf cat who apparently can still hear some high tones.

So I was wondering if a dog whistle might aid communication.

Then I wondered if there was a dog whistle app for a mobile phone.

There do seem to be tone generator apps; has anyone tried one of these?

Those of a certain advanced age and degraded TV watching habits may
perhaps remember Bruce Forsyth and The Generation Game and "HERE KITTY
KITTY".

Technology moves on (I hope).

Cheers
