OK, my last post on this topic.
It's been 10 days since Chongo's release and Radiograph appointment. As mentioned he was released with a clean bill of health. His supposed rehab was to last 5 weeks and he seemed good to go within 5 hours if not minutes.
He is currently pretty much back to his normal self and we are no longer alarmed with his acrobatics. He runs, jumps and flies probably better than before his surgery, and if anything he seems to find more ways to entertain himself without intervention.
The crate is gone, as well as some of the accruements that we left hanging around for his transition. He's a little easier on the other cats, although it doesn't seem to last long. Just enough time to gain their trust and then makes the effort to destroy it.
He's definitely still an awkward teenager, at one moment showing his tremendous athletic prowess and then in the next moment misses so badly you go online to search for cat helmets. Totally like Pee Wee Herman wiping out his bike then claiming "I meant to do that".
Best of all, his interaction with us has become more than just playtime with what he seems to believe are his litter mates. It's not all just a quest for rough and tumble play, but moments where he is happy to just hang out and be sweet purring kitten. Of course that can change in a heartbeat without any provocation and then it's game on.
So thanks again for all the well wishes and help coping through all of this. I could write a guide for how to deal with this but I hope no one else ever needs to. If I were to pinpoint one aspect of his post surgery care that aided with his recovery it was being close to him every moment we were home. Sleeping on the floor was no picnic nor being awakened every 2 to 3 hours, but the kitten that emerged was every bit the happy confident kitten that was crated 8 weeks prior.
