A kit kat settling into its litter is very stressed and attempting to control the smallest corner of its world, which is all it feels capable of. Spend some extra time socializing the babe. Playtime is recommended.
What has changed in your home to make your kitten guard a small territory with such voracity? New pet? Move? All of which can throw an existing kit cat (especially a young one) into distress.
Be glad that you're not dealing with an older cat who tend to exhibit their displeasure with "MARKING behavior" that can compromise bedding (yours), shoes, keyboards and anything the babe sees as important to you.
