My husband found 3 kittens that were about 3 weeks old. They were accidentally transported to the town we live in on a truck so the mother is not around. I took them with the intention of keeping them until they were a little older and then giving them away. I already have two cats. I started feeding them the hartz kitten milk. One kitten got very lathargic and sick and the vet told me that my dog must have hurt him and said there was nothing they could do for him. He was put down. Later that day, another kitten was in the same shape. Long story…..several weeks and $1300 dollars later, the vet could never tell me what kept causing these episodes. Both of the other kittens had several of them. I took them to the emergency vet 5 times. They just kept testing them for every disease out there….they never figured it out. After the last episode, I ran out of the milk and stopped feeding it to them. They never had another episode. I know it was the milk. They are 6 months old now. Needless to say, after going thru that with these little kittens, I now have 4 cats! I don’t understand why this issue isn’t known by the vets. This product needs to be taken off the shelves!!
