Ah --  well now, that's the hard part.  Very often, you can't even get ahold 
of  a newcomer cat -- they're very frightened and wary. So you couldn't get 
them  to a vet if you wanted to.   And then there's the matter of  expense.  
This is a farm.  Uninvited cats come and go all the  time.  One could spend a 
fortune on other people's cats -- trying to  protect your own.  It's just not 
practical.  That's why I was asking  if there's something more than CS that I 
can 
do for my own cats.   Actually, the practical thing to do with stray cats 


 Another thing that would discourage stray cats from hanging  around  is not 
to leave any cat food out for more than 1/2 hour at a time.  Your own cats 
would quickly figure out that they need to be there at feeding  time or else 
miss 
a meal. Cats that don't belong in the group will be run off in  short order 
when there's not a constant food supply.
