In my opinion, a cat shouldn't be left outside all day long... so a Ragdoll is purrfect for me !!!!

What can happen to a cat outside :
Bad people can steal it;
Bad people can kill it if they really don't like cats;
Good people that thinks your cat is lost will "adopt" it...;
Poison, toxics plants, fleas, worms...;
Cars;
Dogs, wolves, coyots, bears, other cats;
A sick cat will go to hide itself and will probably die there.

When you let a cat go outside, you expose it to a very short lifespan.
