I thought all the kittens had some sort of cold as they where making a strange sneezy and coughy noise. I checked them all, all looked well have gained weight and had no discharge. So in my panic i dragged hubby home so we could take them for to the vets....only for him to inform me all they have done is learn to hiss, as he rightly pointed out to me they only do it when i pick them up as soon as i put them down they stop. The coughy bit is like them spitting.....its very cute now im not worried
