My dear friend, Bandit.....
You need to let that other kitty cat know who's the "head kitty" in your house.....we dogs have no issues in this area....that's what all that sniffing of butts and low growling is all about when we get company....it's our way of telling the visitor this is my house.....

That being said, I know you are a friendly kitty and if the other kitty would just learn how to share, I'm sure you would, too. I know your Mommy has taught you how to be the best host, so kill that other kitty with as much kindness as you can muster while he/she is visiting and maybe some of it will rub off on him/her..... they may learn something so that when you go to visit them, you'll be treated the same......if that doesn't work, maybe you can have a private talk with Roe to see if he'll help you get the message across....
Good Luck!!
Your friend,
