Why does my cat immediately stick his butt in my face every time he jumps up into my lap?

hi Eli416
Cats are governed by their own social rules. It treats you like a cat. You seem to be treating your cat as a human expecting it to shake hands or something. Learn some cat.
You can say hello with a slow blink. Most animals do this - except for people.
Best wishes

Does he lift his tail and make it into the shape of a question mark ???

It means that he is happy to see you.
Wouldn't it be great if all people that we meet are happy and stick their butt in the air to show it!

Male cats will try to mark you as their territory anyway they can.. so I guess that includes farting on you

He thinks you are his Mum and wants to show you his butt (don't want to go any further why !)

Maybe he is saying you are a asshole

He loves to your rim jobs?

Cause cats suck

He knows you're a fag

their endstincts

You are the butler

she wants you to SUFFER

I don't know why they do that. Just turn it around.
