Hee! Spud is convinced that anyone coming into the house is there to visit him. He has no shame, throws himself down in front of them and shows his belly, talking the whole time.
On the other hand, the only other human beings, besides my hubby and I, that have ever set eyes on Siam is the vet and the vet techs. He will hide even if he sees someone out the window. He is a scaredy cat!
