People in the comments like “my cat is happier outside” yeah, because you’ve made no effort to make your inside enriching and enjoyable for a cat.
And guess what? Pet ownership obligates you to provide a high quality of life, including safety, for your animals. Even if it means the uncomfortable act of self-evaluation and improvement.
My snakes would absolutely escape their terrariums if I let them. That doesn’t mean they are happier, healthier, or safer if I let them free roam my house unsupervised.
