Hey cathexis,
As MsTinkerbell pointed out, I took him miles away from my home, freed him in some nice woods.
I guess you want more specifics. Here they are just for you.
I put him in a cage, took him to work. I put his cage inside the door but the admin lady couldn't handle it so I found a cool, shady spot for his cage. When I was able to leave, I took him deep into some dense woods and let him go. Seeing him disappear into the bushes caused a softball lump in my throat. I wished him well and to take care of himself. I was really attached to him, he was so funny at times, but I knew I did the right thing.
