Will this cause harm?

[TobleroneBoo]

I have 4 cats, two of which are brothers. One of them my favourite sleeps at the end of my bed every night. He used to wake up around 4 am and nuzzle faces, wander around our heads and lick hands until you bundled him in for a cuddle. He has a love for all things of a certain material ( think blanket, fluffy socks, dressing gown) and loves to suck on them and knead for up to 20 minutes at a time. He's stopped fidgeting around since there has been a fluffy jumper on the end of my bed, but could it be harmful to him?

I've got one who does this. He wanders around the house, trying to eat bits of random fluff off the floor. He tries to eat my Uggs. Have a google of Pica in cats. Siamese are particularly prone.

I give him food that has anti-furball stuff in it, and you can also get a paste.

Keep an eye on him, to see if he's ingesting any.

Both my cats hump fleecey stuff.

Mine love a good suck / chew on fleece. My poor dressing gown looks like a vagrant's. Mine are Burmese so probably prone to pica like Siamese.
