••••(KO) Cats have a scent gland in their cheeks that they use to mark their territories and belongings. This kitty marks his door to let other cats know he lives here. Your kitty may mark YOU as his/her own private property by rubbing gently against your calf or knee! It doesn't leave any mark on your clothes, just a very faint trace of his own personal scent. Not detectable by a human nose.
I thought I was a hamster stupid and Spanish oh Lord oh wanna hear a joke a drunk comes out of the bar and says I am Jesus Christ to two priests they say no son your not drunk:I will show you so the drunk takes them to the bar bartender: OH JESUS CHRIST YOUR HERE AGAIN. but you probably know that the bartender was annoyed.
