My two cats are indoor cats, but my parents' cat Phantom is an indoor/outdoor cat. She stays in the yard, so she's not in any danger of being run over (or annoying the neighbors.
) Most of the day she just sits under the old playhouse or the small shrub by the back gate.
Muffy, the cat of my childhood, also stayed in the yard. She found us as a stray after being dumped . . . she was about six months old and her stomach was so bloated with hunger that at first we thought she was pregnant. Apparently she decided she had a good thing after we fed her and never went off our property again.
The other cat I knew as a child, Dr. Who, was not so conscious of boundaries. In fact, several years after his death we learned that he had previously belonged to neighbors several blocks away! (We knew he had belonged to SOMEONE because he was neutered when he arrived. But we never knew who.) Dr. Who would wander here and there and liked to visit our cat loving neighbor, Ellie Lee, who lived a few blocks down and loved, rescued, and fed cats. Dr. Who also got into fights, despite being neutered, and unfortunately lost sight in one eye because of it.
We kept him inside for two months after that as he healed and he spent a miserable two months sitting by the door all day, trying to escape outside.
When he got old and his vision began to go, he started to get lost . . . we'd find him a few blocks away, just wandering. In the end we had to put him to sleep. So sadly he suffered many common trials of outdoor cats. In his case, he could never have been happy as an indoor cat, though.
If only more cats could be like Muffy and Phantom.
My own cats are indoor only, but I take them out on leash sometimes. Even with the risks outdoor cats face, I can understand why people allow it . . . My cats love going out and are clearly much happier outside sniffing the grass and trying to eat bugs than they are inside, where they spend most of their time staring out the window and boredly ignoring their kitty toys. But I won't risk my sweeties . . . they stay inside.
