Well then you won't have to worry about them clawing each other will you? LOL Just keep and eye out on them gettign stressed with each other because declawed cats tend to bite more so than clawed cats... so just really watch body laguage. I've never seen kittens fight badly, so you most likely won;t have any biting issues between the two - just a warning to keep an eye out. Expect the worst and get the best!
