A friend who is something of an expert on cats suggested a way to introduce a new kitten to established house cats when my daughter rescued a tiny and very grubby kitten that was probably too young to be away from her mother (kitten, not daughter). She (friend, not daughter or kitten) suggested dabbing a little oil from a tin of pilchards on the back of the new kitten's neck and giving the pilchards to the house cats. The idea was that the cats would eat the fish and then lick the oil off the kitten's neck and everyone would have got to know each other in a friendly way. Dylan and Pepsi (house cats) guzzled the pilchards and shot out the cat flap, completely ignoring the kitten. After a couple of days, the kitten who was destined by absentdaughter to have some sort of girly name, started to smell awful and I remarked that she smelled like rancid fishpaste. Fishpaste she became and remained so for the next 17 years.
