females will settle better in my experience (all our three are female), he will find some old lady or gentleman to bully in the near future I am sure good on you for persevering its one more with a good home.
your tale makes me very jealous
while we lived in Wales we had a similar tale
a cat that had been dumped in the village eventually came to us like you we fed him ..........for 8 years , I tried every trick in the book but he would not let us near him, even though he had his neck ripped out...
and you might try rescue remedy on the tips of his ears or a few drops in his water
male cats take a little longer to settle
my advice would be ignore him and if its only you then you feed him for a while
do you know any of his history, because if he has been a stray this might account for his...
is the correct answer
I have had cats all my life
and still never found out why they do this
we have had several cats that adore coconut
they are very weird animals
