All cat owners are familiar with this behaviour. Cats rub against your legs, furniture legs, doors, corners of walls...pretty much anything. As I understand it, this is to show ownership (we all know they OWN us).
Cleo does it constantly...she wakes me up by rubbing my hand, and does the same as I fall asleep...she also regularly rubs against doorways and objects. But...maybe not surprisingly...Toby doesn't.
Do some cats do it more than others? Does it warn other cats away?
Maybe he feels that his sister scares the ???? out of him and he doesn't want to upset her.
Cats are too complicated for us humans to understand. My two were litter-mates but it was like a constant war zone. Frankie was a mummy's boy but Princess Merlin was stupid and vicious. She was sometimes very loving.
I came to the conclusion that male cats are far more easy going than females. Yes, girly cats can be loving...as Cleo is...but they are also little terrors and moody.
That reminds me, I have a new photo of the little Madame that I could post.
There was a drop-dead gorgeous temp Greek Vet at our practice (my pal and I were old enough to be his mother but he was lovely).
He took ages talking to Merlin and coaxing her out of her carrier. He asked me to hold her neck whilst he did something to her. She got out of my grasp and lunged at the guy. I tried to get her before she attacked him. She got me instead.
The Vet said, 'put her down on the table' he seemed to have completely missed the fact that she had her teeth embedded in my arm and there was blood coming out of several holes. He had to clean and bandage my wounds.
He went back to Greece to open a Cat only clinic?! He must have been nuts.
