Sometimes Pepper will start choking after I give him his medicine. He stops after a few seconds. It was scary at first but now I just watch him to make sure he's okay. I've also given him some furball medicine and that seems to help. I would also feed the cats in serparate rooms. When Pepper was little Storm would try to eat all of his food. Later on Pepper wanted Storm's food. When Pepper was about 6 months old I gave up and let them eat each others food. Good luck.
