We once had a neighbour who had 4 cats, 3 dogs and a rabbit! I got absolutely fed up with having my seed beds destroyed night after night that I went out and bought 4 ultra-sonic cat scarers. It had a bit of effect but not enough (seems one scraggy old moggie was deaf! and our grandchildren complained they could hear this constant high pitched squealing every time they went down the garden). I then invested in a 'Mosquito' and a roll of orange electric fence wire + a bag of insulators and set up a criss-cross pattern over the raised 'seed bed'
** A Mosquito is a low powered domestic electric fence kit that gives a single pulse of high voltage but extremely low amperage electricity and runs off a small 12 volt battery.
At around 12.30am there was a double Yeowwwee! from the bottom of the garden followed by a 'clang!!' On inspection next morning there were 2 divots in the seed bed but very little damage to the seed bed (the clang was said moggie scrambling under the back gate in its rush to depart from whatever it supposed had bitten its rear end). The 2 divots were so placed you could see it had come over the dividing wall, leaped immediately into the air and landed about 3 ft away on the same patch (hence the double Yeowwwee") and then escaped under the gate.
We were then trouble free for about 3 months but I had to remove the 'Mosquito' and its associated paraphanalia because as the plants began to grow they would touch the wire and the wire would cause the leaves to spark & shrivel.
The neighbour moved away about 3 years ago taking said menagerie with them and although there are other cats in the locality we don't get the problem any more just so long as I remember to re-charge the batteries in the conventional cat scarers regularly and remember to switch them off when the grandchildren come around (& back on again when they leave!)
