Weird. And kind of wrong.
Cats should be free-roaming. They shouldn't be confined to a flat or walked on a lead.
We have 3 cats, all with different levels of freedom based on their intelligence and independence. One goes out every day and whines if he can't (he goes out and murders anything that moves), one that goes out then comes back and sleeps but he isn't really arsed what he does tbh, the other is young, easily startled, a total dope, not very agile for a cat and if she gets out just panics and runs back in.
In short, cats do whatever the **** they want. Humans like to think they have some say, they don't.
Cats on leads? The cat is taking you for a walk
