Apologies to Stringmaker for Hijacking this thread - and my Sympathy for his friend.
As an explanation - It's got to the point where Cats are a very emotive issue for me down to the amount of scat I have to pick up in the garden. I struggle with the concept of feeling it's OK to buy a pet then not know where it is or what it's doing, even where it's doings are. I find it quite selfish and struggle to understand why other people think it's OK - hence I get het up about it. I get even more annoyed when people suggest I should fork out on spending money to try and keep domestic cats off my own land. These cats have owners - the responsibility (and therefore expense) should lie with them.
No apology needed and thanks.
I get what you are saying; in the terms and context you use you could say that cats are not suitable animals as pets because it is inherrent in their behaviour to wander and roam and therefore it is impossible to control where they are. When their presence is unwanted, and their calling card even less so therein lies the problem.
It all stems from us switching from hunter gathering to farming; if the Egyptians hadn't deified the things for protecting their grain we wouldn't be having this debate. Or then again maybe we would; the issue this time wouldn't be domesticated cats but feral ones?
