A button and two needles

There was a baby rattlesnake outside yesterday. He was very big compared to the ones I've seen in the past. Rattlesnakes give birth to live young. They are defense-ready with fangs and venom but, the rattle is not yet a rattle...just a button. Every time it sheds its skin, it will get another rattle. This will happen many times per year...thus, the snake's age cannot be determined via counting rattles. The venom is full strength, though...so, please be careful.
