It sounds like the Callooh Zoo! (Do you charge admission? - I mean to people.) You must truly like animals. Where does the chipmunk actually reside when it's not eating?
It's a bit wordy, more like prose than poetry really, but it paints the scene very effectively. Reading it makes the depiction feel very homey, and very much like the autumn. I liked the "dining on sunshine" line the best.

Actually it IS a zoo (2 cats, 2 dogs, gerbils, rats, fish, and children are domesticated residents - mostly domesticated anyway). Normally I feed the chipmunks and squirrels etc OUTside. I truly love animals (including my children). I give animal magnitism a whole new twist.
Maybe I sould put in prose form... perhaps the line breaks are too jaring -- thanks very much!

Make it a prose poem, I think. Maybe tighten up the words to make it more poetry. I love the images you draw - eg the cameo of the dog's reaction.
The chipmunk is an omnivore. It prefers seeds, nuts, and acorns, as well as fruits or berries; but it also eats slugs, insects, spiders, nestling birds, eggs, and occasionally mice or small snakes, according to the internet. Dogs are also omnivores so dog food in moderation should really not be a problem. (In fact reading the above by dog will eat everything on te list except snakes (never had the opportunity) and acorns (too hard to bother with) She LOVES slugs - very handy in a damp climate but quite disgusting to see.
