My HVAC Boy

So I was sitting in my living room watching TV minding my own business when I heard a noise coming from the basement that sounded like someone was working on my heating, air conditioning and duct work. Since I knew I hadn't called a repairperson I immediately had a suspect in mind. I checked in my bedroom and sure enough Thompson was sitting peacefully looking out his favorite window and Theo was looking mindlessly off into space perched on his favorite chair. Diego-san? Nowhere in sight.

I ran downstairs calling his name thinking to myself he had somehow gotten trapped inside the duct work. My basement was semi-finished (framed and sheet rocked) last summer so most of the furnace and duct work is not nearly as accessible as it used to be. I peered behind the furnace but could only hear Diego not see him. I scolded him and told him to come on out. A minute later he appeared above on the framing to where a bathroom will go if I ever do finish off the basement.

I have no idea what he was up to, what he got himself into. Further I have no idea, how Diego-san, the boy who gets into everything got himself up to an area above my head but without anywhere I can think of that's easily accessible by a leaping kitty.
