my Junior does that too! He will attack all of a sudden!
he will look at my arm intently.....maybe he thinks it is a piece of fat ham! LOL
AND......scratch at my arm furiously using just one paw! like he is is trying to tell me something or getting my attention. I will always go with a big OUCH! n he will stop what he is doing. look at me again with that small brown eyes....
n start again! I'll grab him for a big wet kiss and he will make himself comfortable on my lap. just like a baby. maybe he just wants to climb on my lap yea?
