Has it occured to you that it is really up to him what happns to Conan?
Possession is nine-tenths of the law, and the cat is in his possession. He
took her from the shelter and took her to the boarding kennel.

So regardless of what Monica and her imaginary friends want to do, the bag
is in his lap, so to speak. Just as it always was from when he first agreed
to go and pick Conan up. Dan is the only person responsible for Conan still
being in a cage and not in a warm and wonderful home.

Dan is the only person who can still make this right.
