Well I leave my cats indoors, they are rescues.. All has been fine have always kept them indoors.. I use to let cats out but they got in fights, would not come in at night and I got LYME!! Have had cats my whole life (67) they are my kids.. Living in a rental and door does not shut properly. It looks like it does then just now my cat got out..HE LOVED IT!!! ran to a tree and just was happy as hell. I freaked, he said OH I"M IN BIG TROUBLE!! I ran after him he stopped and knew he should not be out... So now he's meowing all the time to go out ( spring in Connecticut!!) he's like a child but I have no kids... I want the best leash on the market, so I can take him out... I researched them all but none seem that great.. Any ideas?
