Ugh. I cannot believe this, buy my former feral is throwing up again. He was diagnosed with giardia and lung worms, took a de-wormer for 3 days. And was much better for two weeks. He has now begun throwing up again--and he has been strictly indoors with no other cats except the kitten, who does not have worms and has been de-wormed 3 times. I have a vet appointment for tomorrow, and have NO idea how I'm going to get him in a crate. But I'm being like Scarlett O'Hara, and I'll just worry about that tomorrow. My question is, is it possible the de-wormer did not kill all the worms, and they came back?? I am so sad about this. The poor guy can not make any progress with his shyness b/c he gets so sick and when he is sick, his instinct is to hide...which he is doing right now.
