I currently have two cats and I am going to get a kitten from a friend of mine who's cat just had kittens, there is just one problem. One of my adult cats has a sensitive stomach and throws up a lot to the bewliderment of me and my vet. This has been happening for a while and has gotten better since I switched to purina sensitive systems. My other adult cat eats it just fine and has had no adverse affects so it is simple enough. But now with the kitten I am going to need to get special kitten food to ensure the kitten has proper nutrients and there is no way that I am going to be able to constantly watch who is eating what and when. I am wondering if there is a specific kind of kitten food that is for sensitive systems so that if my finicky adult cat eats it, it won't make him riddiculously sick? I can't afford wet food all the time so I buy dry. My girl cat won't touch even human tuna out of the pouch, let alone cat wet food... Any suggestions?
