Mine are inside 90% of the time, excluding the dogs who love being outdoors with my brothers while they do parkour or something.
We have two cats who want to be outside, a 2 year old tabby, and a 12 year old orange and white cat who want to be outdoors, but not because they like it, because they want to escape. They have gotten out twice, but came back both times. My dad built a little house for them to be in, and they love it. However, the annoying strays bully them while they are in it. Elijah, the 12 year old, has a sister, Ella, who loves being outside, and we let her out in our yard, but she just wants to lay on the deck and under the chairs. She would never escape. Oliver, the tabby, has a sister, Electra, who now wants to get out, only because Oliver showed her that he can get out. Hopefully, she would never leave us. We also have 3 other cats ;; Ezra, Snow White, and Belle, who would never even go NEAR the back door. Ezra is WAYYYYYYYYYYYY too lazy, and Snow and Belle are 10 year old white cats who both have health issues and dont even like going downstairs. The fully inside cats are terrified of the outdoors as well, so they wouldnt wnt to go outside anyway.
