* Sophisticated detection system, which detects and repels cats, without harming them
* Protects lawns, flowerbeds, bird feeders and ponds.
* Easy to install
* Weather resistant
* Requires two 9V alkaline batteries (not included)
I suggest a couple of 9v rechargable batteries from somewhere like 7dayshop to save having to keep buying new batteries.
Works for most cats, some seem deaf in my area, kids dont like the sound much either ;-)
