Does anyone else have this problem?

When I am relaxing laying down watching television my cat quickly jumps on me and positions itself over it and starts slowly jiggling why does it do this?? Or sometimes I'm woken up with this happening...

It's been neutered and is about 4 years old. Any help appreciated

It thinks it's its mummy's nipple.

It's likely it is only kneading and not realising what he/she is kneading on.

I don't think anyone really knows why cats knead except they do seem very happy whilst they are doing it.

It must be tiny.

do you try and stop it or let it carry on

Stop putting kit-e-kat on your balls then.

Maybe he enjoys it...
