I found some kittens about 3-4 wks old. They were fine until last night when i got home from work my boyfriend told me there were worms eating away one of the kittens. I was stunned to hear what he had to say. He picked up the cat and to his suprize it was filled with granular sized worms. WHAT COULD BE EATING HIM ALIVE, i'VE NEVER SEEN THIS?
