I have purchased two of these, the cat problem in my area has been steadily growing over the past few years, and many native species of bird and reptile I used to see around my yard have disappeared with the increase in feline numbers. Not only this but they also urinate on our front porch leaving a horrible smell that seeps into our living room, I figure its time to take some action.
ssssnakeman: I think they are the same size as those used by the council, there is anothermore expensive trap listed on ebay ($100 for that one) that is only 2 cm wider but same for other dimensions and the add claims for which states that they are used by professional pest control.
