Ya say ya want a revolution?

This is Mao. He says his name a lot.
Mao wandered up to me as I unloaded groceries from my car, and wouldn't leave. He followed me around, going "Mao."
So I fed him a plate of tuna.
I think he could smell a sucker.
He kept up the "Mao" sounds.
Tried to follow me in the house. Nope.
I took him (her?) to the back porch, and fed him/her another plate of tuna.
He/she stopped going "Mao" to eat. So, while he/she was eating, I said "Mao."
He/she replied (not kidding) "Mfff."
I'm not sure if this is a neighbor's cat - I suspect it is. Way too familiar with the ins and outs of a house, and way too eager to go inside.

That or he's a refugee, and I've just developed a cat.
