I moved house several months ago and discovered that my new house came complete with a family of feral cats - a mum and two small kittens. With the help of a local charity, we have had them all neutered and we provide 2 meals a day in return for pest control.
I've noticed them all scratching a lot recently so I'm assuming they have fleas. Is there any way to flea treat feral cats that will not allow themselves to be handled at all?
