Cat Troubles

My friend has just moved down the road from me so I am very happy about that.  They have ‘adopted’ a cat that keeps coming in their garden buying it food, toys, a basket, a sparkly collar and even flea powder and worming tablets.  I don’t know what its owners will think when it comes home with a new spangly collar (but it does have a bell on it which will hopefully save some lives).  I was tolarating it and even played with it for a bit, my opinion of cats slightly chaging until we were sat on the patio and it ran past with something in its mouse :(  I was told by my friends to leave it to it but how could I when it was wiggling.  The cat looked into my eyes and squeezed with its jaws and blood dripped on the floor.  I then managed to pick up the cat and it droppd the rodent, but then I dropped the cat so it picked up the poor little shrew and started to swipe it with its claws again.  Finally I managed to resue it with the help of a flower pot and put it in a box.  It did not look that damaged apart from one blown eye.  I think it was a bank shrew.  After a while in the box it appeared to perk up so I took it home.  This morning though it was just lying there on its side kicking its legs out unable to stand.  Perhaps I should have let the cat finish it off, but I would have felt very guilty about it.  I suspect that although it was able to run and jump last night it will be dead by the time I get home :(  My friend promised me that if the cat bough live birds home she would phone me what ever the hour and I could go round and rescue them.  Needless to say, I am not going to make friends with that cat after all.
