anyone have any ideas on how to get rid of cats hanging around the factory environs? Unfortunately there are a number of domestic dwellings in close proximity so we're not sure if they are domestic or feral (I have a complete cat phobia so I'm going nowhere near them!). We're trying to find out but regardless it won't matter when it comes to keeping them out of the site. Does anyone have any ideas that worked for them and don't involve guns (which has been suggested )? Are the ultrasonic things any good? We have a large boundary but I guess we could just use them around the building itself rather than the entire site.
