I may not completely agree with your inside outside view of cats completely (though I do to a point) but everybody has their own opinion and if the cat is happy and healthy to each their own. Some areas it’s ok and in some areas not. But I did want to say you know that you did an awesome thing by adopting those cats. The ones that are way up there in age almost never get adopted and it’s so sad. You did an awesome thing for those cats and it’s heartwarming to hear that at least they can spend the remainder Of their years happy and being loved
The only bad part of it is I now have 5 senior cats and 3 senior dogs. Way to many seniors at one time and it won't end well. My heart breaks just thinking about it.
