Soggy kittens are annoying. I have no idea why people are so into this helpless boy in peril thing.

Medications have side effects (especially the ones used to anxiety/etc) and therapy has limited success with very smart people. It takes just one bad therapist for him not to trust the process.

..and he could just consider ocd his cross to bear. That thing he just has to learn to cope with. Medicating might seem like giving up.
