Gareth Morgan. The wallaby issue is indeed caused by safe for them,non controlled areas. Cat issue was identified a long time ago.would be more than 25 years.there was study going on in area..THINK of one wee native bird,a cat went through and decimated numbers,when shot? Trapped?? Was found to half numerous bits of said Tweety birds inside. The cat ladies have been around since forever,so has dumping of kittens.... Until we have a no questions asked zero charge,drop off and go service to remove unwanted cats..and dogs for that matter,the dumping issue will continue
