As you all know I have an indoor kitten named Emma... I know all the potential illnesses of an outdoor cat and all the risks ... However my boyfriend has always had indoor/outdoor cats ... They recently had his 17 year old cat PTS and next year he wants to adopt another. The problem is I do not want an indoor/outdoor cat too many potential illnesses its not really best for them. Emma is harness trained and gets supervised out time on her harness. The thing is we live together and I dont want his choices affecting my cat but at the same time the new one will be HIS not MINE so I really cant tell him what to do with it ... Maybe it will be ours? Idk but anyway how do I convince him indoor only is best for their health when this is all he knows and I dont want to put down how they cared for their last cat.
