So you let your cat roam, knowing that it being killed prematurely by something is a good possibility, but you don’t care enough about it to prevent that from happening.
I live in the country and have had my cat for 8 years. It started out as being an inside cat but once it started going outside it preferred to be there. Cats love to roam and hunt. He generally sleeps in a box in the garage, even thought my girlfriend bought him this little “cat house”. I care enough about the cat not to try and keep him cooped up in the house all day when he would rather be outside chasing chipmunks.
