It’s been my experience the prime desire to keep a cat indoors always is longevity (getting hit by car, fights with cats/dogs, exposure to disease). Cats are territorial and natural hunters. Some cats do much better outside.
I had a feral adopt me. She had kittens. They had no interest in being inside my canine smelling house.
One of the grown kittens moved next door...the other went to that big litter box in the sky.
Although MaMa kitty is very cagey, my canine loving heart slipped into “protect” mode and thought I could convert her to an inside kitty. You know, keep her out of the elements and away from danger.
Very BIG mistake on my part. Aside from damage to my home while she tried to escape...the sounds she made sounded like I had tied her to the railroad tracks and the Number 9 was speeding toward her.
She won the battle. I feed her and pet her when she allows it...and pray for her safety. She is happy.
