Just a quick update, things are going extremely well right now. The crate thing is pretty much figured out though less than ideal. Chongo will play with me through the crate as opposed to always needing to open the door. His calls are no longer distressed or bordering on angry, just rather quietly asking for attention which he is continually granted.
Trish stayed with him all day yesterday and he was very well behaved and it seems like I am the instigator to some of his more robust crate behavior. Takes his medication without any fuss and is more willing to stay put for new food and water (his crate at the surgery facility had the label escape artist on the door). In all we're just extremely happy he isn't giving us much grief while at the same time still being the very spirited kitten that made him stand out amongst his litter mates.
As for getting into the convalescing crate business, it's not in the cards for me. What I do plan to do is contact one of the premium crate vendors who also sells additional parts and order a custom one. That way they can either place it on their site to order or I can at least place the details of how to obtain one in a separate thread. The three really important things are width that coincides with the length of a litter box so as there aren't any pinch points to get caught up in, Height limited to around 20" so it doesn't promote climbing (better they need to duck than climbing the sides) and dual doors so you access litter easily. Perhaps a slide in divider that would make maintenance easier, just need to see how things go.
Again, I'll post a separate thread as I get the details nailed down and see what Chongo has in store for us. As mentioned, things are going well right now and many of the issues we were having have been remedied. Also, it certainly helps to have a patient that's being cooperative no matter how much he wants to breath the air of freedom that resides right outside the door of his crate.
