FWIW I have just installed an animal "repeller" which comes highly recommended from those who have tried it. I bought 2 via E-Bay at 1/3 of RRP as I wanted mainly to discourage cats from emptying themselves in my raised asparagus bed. However I am told that it also repels squirrels, foxes, dogs and badgers without hurting them. It's a sonic thingy piched at a discouraging level for our animal friends which can be directed to cover an area stretching about 85 ft. It hurts neither them nor us. Furthermore, I believe it also affects wood mice, bank voles, rates etc. - but, sadly, not underground! My asparagus bed looks rather like a piece of Swiss cheese, being riddled with rodent holes which is why, originally, I wasn't too concerned about the feline visitors. Traps will work for the mice etc. but they breed so quickly that I doubt the long term effectiveness of the old spring trap. Human wee certainly works but it's not the most appealing method of control.
Having put up the "repeller" yesterday it has certainly proved effective. No cat visits - but I guess that's possibly something to do with the 4 ins of snow apparently triggered by my new gizmo in this part of Dorset :-))
Will post a more considered evaluation after a week or two if this would be helpful to the group.
