I'm going to be glad if he will take one capsule a day. I got the human formula rather than the pet formula. I think it says 2 capsules for a person. Since he is only 15 pounds now, I think one for him will be plenty. They said that there hasn't been a case of an overdose. He gets a bit of canned food in the morning and in the evening to supplement his dry food. I think if I can add the TF to one of those feedings, I will be happy. She mixed the suspension so that 2ml has one capsule's worth of transfer factor in it.
