Have you had the cat repeller long? I have several around the garden and they work a treat.
Have read, that when installing a sonic cat repellent, the cat/s will sometimes confront it and try to ignore it for a while, but it gets to much for them in the end.
I wonder if your sonic cat scarer is in the right place at the right height ect.
