A friend of mine recently bought a house and with it came 14 barn cats. She has been feeding them since January. Now, in the past week, they are all dropping dead. She said they are literally falling over dead. She even had a litter of approx. 2 week old kittens. Their mama died. So, she took them in and was bottle-feeding them, for a week. Then, they started being unable to drink, all of a sudden, they were choking on it. That afternoon they died. So, her question, and mine, is, "what's going on?" Does anyone have any ideas? They have 4 adults left. Thank you!
