It depends on the cat. I had a rabbit when I first got my first kitten, and they got along great, but my cat was very laid back. If you can keep them separated while you are gone, and watch them when they are together they should grow to respect each other and the cat will should realize the other animal is part of the family and not prey, but don't count on it.
Truefully, as long as the kitten has enough things to play with, he should be fine while you are gone. He will explore...definitely! Nothing you can do to stop that. And the toys don't have to be expensive or store bought. My cats can amuse themselves for hours with just foiled balled up. Honestly, cats sleep most of the day, and as long as you give him a lot of love, attention and play when you get home he should be fine. If you're worried about him being lonely while you're gone, the best bet would be another cat rather than a smaller animal. I think cats are like tattooes...once you have one, what's one more?
