I wouldn't worry, but you might want to mention it to the vet next time you see
him/her. When one of our cats was a kitten, she did hiccup occasionally. My vet
said it was normal for kittens and cats to get the hiccups sometimes. Some get
it more than others. I think with young kittens, it can be from eating too
fast.
