Our cats are all indoor-only rescued kitty cats. Because we knew they would appreciate some fresh air, we enclosed one of our patios (it’s now a “catio”) which lets them be outside, but safe and enclosed. Indoor-only cats live longer, safer lives.
Good for you except...
You are propagating a stereotype by your use of the word “kitty”.
So now, if I do anything at all to try to keep SOMEBODY ELSES CAT away from my house, I’m worse that someone who boils small children and eats them on rye bread or something!
If your cat was twice as big as it is now, and you were only half as tall as you are now, you would not be the “owner”. You would not be the “master”. You would not be the “caretaker” or the “friend”.
You’d be the “lunch”!
These are just my thoughts and are not aimed at you. But there are alot of cat owners who should NOT BE cat owners!
