Are you seriously telling me that a domestic cat can not survive outside?
ok, i'll bite on this one.
as some of you may be aware, i recently had a cat run over on me, but that's besides the point of this conversation.
the way we got him was he turned up as a stray at my aunts house (one of these people who just accumulates cats), she had been feeding him for a couple of weeks.
and even then, when we turned up to take a look at him he was wretched, scrawny, bad ears, bad feet bad fur (what fur there was), he was about 1/3 of the weight he should have been.
now when we got him it was plain he wasn't wild, he'd been domesticated and was easily handled, but you'd be amazed that from this scrawny mess came (after considerable feeding over several months) a happy healthy loving cat.
so you say a domesticated cat can survive on its own? i doubt it, yes cats have a wild instinct in them but a cat that's been raised domesticated and mollycoddled its whole life is NOT going to survive well outside, had it not been for him finding my aunt and then us, he's have starved to death.
as it was he had several months of health and happyness, we treated his ears, he tripled in weight and his feed healed up, until sadly he was hit by a car (which was massively unlucky).
feral cats get taught to hunt by their parents, but a domesticated cat is going to have to learn from scratch, with no intuition. if you want to know what trying to survive from scratch is like maybe try out to go on the island, although that's got medical backup a cat on the streets isn't going to have.
