Purring/vibrating- Pepsi

Loki does it too, Thor is too calm for it but Loki is always running and trying to get his nose into everything. He only really does it when he's somewhere new or exploring something I put on the sofa for him. I think it's some sort of curiosity mixed with hyper happiness.

Sorry to revive an old thread, but our male syrian also does this. It seems like he is vibrating his paws, like testing the surface he is touching/standing on. He doesn't do it all the time, when he does, he seems more curious than anything else. It's definitely not stress/shivering, he's only 'buzzing' his feet.

Just our two cents.
