I have a kitten I had gotten from a friend on Monday. I brought him to the vet on Tuesday and he was prescribed dewormer for 5 days. The vet warned us about throwing up and pooping out worms. But I can't help but worry. He has trouble feeding from the bottle so it takes upwards to 40 minutes to get it all down but the vet said I was doing everything right. I'm feeding him 3 1/2 tablespoons (the whole bottle) of KMR every 6 hours. And today he threw up at 6am and at 12noon when I fed him. And also at 12noon he had so much poop on his own (he just started pooping without stimulation). He also has a lot of gas but every feeding I burp him. Today also i noticed he has a stuffy nose and I hear it when he's awake only. He stopped mewing everytime I hold him too and didn't make a sound when I had to clean his butt. Is he doing okay? Are these just side affects from the dewormer? Nothing was wrong yesterday at the vet.
