Can you go at a time your not working? (lunch...break, after work).
I suggest, cat carrier, door open.
fresh alphalpa grass on the INSIDE with a drizzle of honey on the end..nearest the back (think lure him to the back of the carrier placement of things).
place a little trail leading UP TO the carrier..and wacth him eat his way into your carrier. When he is happily munching on the alphalpa and honey treat. CLOSE DOOR.
whla la...hops is yours.
Ps: a less "sticky" option is strawberries instead of the honey.
