Fine then! Let you cat be miserable and cry at the back door or even worse or maybe better to the people opposed to this training system and probably let there cat/s run wild, let your cat go out so it can get attacked by a dog or another cat or ran over or shot out or even thrown rocks at by children or even cruel Adults. Some people hate cats and will do these things.

A cat would rather be able to do what comes natural to them and roam outside every now and then rather then be couped up in a house getting fat.
