My cat had 4 kittens a week ago. Now I have seen a black thing what I don't think is a flea and looks more like a mini forky tail bug , but I have been told all kittens are born with fleas and I am on he verge of a break down as I have 2 cats and no spare cash to pay for frontline as that is what I swear by! HELP! My kittens are 1 week old now.
