Alvin!

Last year we had a chipmunk that used to come on our front porch from time to time, and would drive the cat crazy. ( We have a full glass door, that Oliver loves to sit by and watch outside)
We called that chipmunk Chippy. This year I think her children have arrived. We've seen three of them running around in the woods next to our house. However, there is one that spends most of his time on our porch. We see him there daily, and he will often spend an hour at a time near it.
We've named these three, Simon, Theodore and Alvin. Of course, the one that always visits is Alvin. He brings seeds onto the porch and eats them, he runs back and forth, will jump down and come back, all the Oliver's consternation!
One day Oliver was crouched way down, tail flicking back and forth as he watched, only to have Alvin come running against the glass door. Alvin may be a little too brave for his own good!
The other day I laid on the floor, to get a cat's eye view of the action:

Here's Alvin, right on the edge of the porch.

He comes closer, while Oliver keeps watch.

"Hmmm - this maple seed is quite tasty, and don't you think I'm cute?"

"Na,na, na! You can't get me!"

We're finding this quite entertaining!
