Nathan is at that stage where everything in the world is DELICIOUS! Nothing is too metallic, or fur covered. One would not want to miss out on something TASTY just because it wasn't FOOD! Nutritional value be dammed! You never know where you might find something nourishing. Places such as...
Harry's Little Red Racer Wagon!
The cat bowl!
That door jamb!
All over the carpet!
Luckily, he is only scooting backwards, but he is fast! And determined! To taste everything! So, don't stand still too long, unless you want to be savored. You might be just the snack he is looking for!
