[alt text: an illustration of a person with a head-empty expression on their face, who is saying, "Not letting your cat outside is CRUEL!" Around the person are various gruesome scenes of different cats in distress. From the top and going clockwise, the scenes include: a cat being carried away by a hawk; a cat that is on fire; a dead cat in the road that has been run over by a car; several dead kittens; a cat that is missing an eye and various patches of fur; a cat that is feasting on a songbird; and a cat that is being carried away by a coyote. The person appears to be completely oblivious to these scenes of distress.]
You simply don't understand cats and their needs. You are also obviously very highly prejudiced and unlikely to hear anything someone like me might say to answer your question.
That's a funny way to spell "educated". Nothing I am putting out here is my opinion - these are objective facts. All cats can get enough enrichment without being let outdoors, and there are plenty of ways to give a cat outdoors enrichment without just leaving them unsupervised to go and get run over by a car. If you disagree with me, you're gonna have to provide hard evidence to change my mind. Like actual scientific studies or the medical opinion of at least a few vets. Because that is what my stance is rooted in.
