Just remember, like humans, animals are succeptible to pain and age. In other words, they can also hurt from extreme noise and possibly even go deaf from extreme exposure. Also, as they get older, they tend to hear the higher frequencies less. For this circuit to damage anythings ears, it would have to be held in very closs proximity for extended periods of time. The cat/dog is well gone before this has been acheived, that is of course if the animal actually heard the noise to start off with. A more effective frequency range for cats/dogs is 20-30KHz.

Hopefully you circuit no longer works (possibly another reason the cat no longer responds), but if an animal runs away it is either scared or it's painful! You should only use this circuit at a distance. The cats run away for a reason just like you would if someone put a air horn in your face ! You have made your cat DEAF !!!
