Why indoors?They have lived outdoors millons of years before us and lived ewhen there were animals around every corner that were danger to them!All my cats live outdoors 100% of the time! I have 5 little kittens and not a one of them are even touched!There are foxes,and dogs everywhere but they are o.k. Cats shouldn't be inside because its not their natural habitat.It can also make your house nasty,all that fur everywhere! Yuk!Kittens learn from their mistakes everyday. They learn to climb,play,fight,eat.If anyone agrees with me,send me a pm!Gosh!People these days!
