My cats stay indoors all the time. I used to live out in the country, with land, and it was a PRIVATE dead end dirt road. I lost two cats (Kelsey and Max) to cars. Chelsea disappeared one day and I never saw her again. Boo came home with a broken pelvis after being gone a week, and Bo disappeared for 5 days once. Plus I had to deal with ticks and fleas on my cats.

They may be happier outside, who knows. They don't have it too shabby indoors, I buy plenty of stuff and spend lots of time playing with them. My cats are not disposable, and I grieve deeply when I lose one. I made up my mind, for both my cats' sake and my own personal well-being, to keep my cats as indoors only.
