I try to give my furries the best of the two worlds. They are inside cats who can go out into my garden, which I have surrounded with sturdy 8' fencing with a cat barrier on top that reaches easily 14 feet into the air. Also I dug a trench around it 2' deep and sank chicken wire, so no burrowing animals can get in. My cat cannot get out, and no strays or other animals can get in.
I learned my lesson a couple of years ago. All my cats were inside except one. He was a stray who ws on the property when I moved, and it took a very long time to gentle him. At first, he went outside during the day and came back to sleep. I left the garden gate open for him so he could come sit on the porch.
I came home one day to find him bleeding and almost dead. He'd been attacked by a tom, fought for his territory and lot. After that, he never left that garden again.
A friend told me that two of her cats have disappeared. They are outside cats.
I am all for inside cats.
