lol, no Pusskin I missed word out - she should NOT be throwing......
TWR - I accept that the cats shouldn't do this and consequently, we have taken measures to prevent them (ie a 2ft high screen above the fence to stop them with prickly stuff). Also I spend all the daylight hours out there (not because of the cats, but because I like to be outside) and I keep the cats away from that end of the garden. I can't police other people's cats though. Even so, she shouldn't scoop up whatever she finds in her garden (together with stones and soil) and throw it over the fence and never mind whom it hits. Not on.
