Terror Strikes The Post Office

Posties have stopped delivering mail to a house because they are afraid of being attacked by an elderly family cat of 19, though his age hasn't stopped him terrorising the local post office staff.
During the last month the cat is said to have attacked 3 postmen after lying in wait behind the cat-flap. 
His owner stated "Royal Mail said they will not come near the house because the cat is dangerous. It was funny at first but it is going a bit far now - Tiger is 19 years old. When he sleeps he dribbles, he snores in his sleep and he sleeps for 20 hours a day. If he climbs up a tree he is done in for the rest of the week. I find it really hard to believe."   It begs the question whether they are men or mice, and whether mice would have an easier time of it with Tiger.

The owner has to collect her post from the local sorting office.  Perhaps it is all the postie frightening that has him so worn out.   I'm going to have to say it, aren't I? The great big soft jessies, scared of a pussycat - they'd probably be braver if they were mice, because I can't believe men would be scared of a cat.
