Answer
Kelly,

There are a couple of reasons that your male keeps attacking your kitten - first because it's not uncommon for intact male cats to try and kill offspring that aren't theirs. Your best solution is to keep the kitten separated from the older cat and have the older cat neutered - you should be able to reintroduce them in a month or so once the older cat's testosterone levels have dropped some. Also when you bring a new cat/kitten into a household with an older cat or a kitten already in residence you can't just stick them together - cats are very territorial by nature and they need to be introduced slowly over the course of 2-3 weeks starting from behind either side of a closed door. For more information on proper new cat/kitten introductions please check out my previous answers on this subject. If you have any further cat related questions or concerns, please feel free to contact me again - I'm more than happy to help in any way that I can.

Kind regards,
