OK here's the epilogue for those following...
That apparatus I posted pictures of yesterday did its job, and Hobbes is back inna house.
Hobbes inna house!
I had to redo my murky meld of two poles extended with gaff tape and plastic ties and extend the whole thing a few more inches in order to reach the next highest branch, since he refused to take the 3-foot leap to where it was yesterday. Did all that, brought some fresh food for the bowl, and got it to a slightly higher branch which he
finally coaxed himself to check out -- but he would only go in halfway (front paws only). I figured this was as close as I was going to get and started moving.
Now I wasn't at all sure how this gangly thing would behave at that extension now that it had seven pounds of unpredictable cat movement in it, but I went ahead and lifted, and managed to get it to the next lowest branch. Hobbes was still hanging his ass out the side of the basket. Now comes the rest of the journey -- no more branches as pit stops on the way down.
There really wasn't a way to detelescope the thing so it just had to swing in an arc from vertical down to horizontal. It took all my strength to keep it from swaying completely over to the side and down from way up there, which would not have been good (for one thing there are lots of locust saplings below with extremely sharp thorns). And I'm still on the stepladder doing all this in order to reach the height where he was.
I get it stabilized and start lowering until the bottom of the pole touched the ground and the only thing left to do was swing in an arc as far as I could while still keeping him horizontal. By the time he and the bowl dumped out, he was maybe 8 feet above the ground -- and true to feline form he landed squarely on all fours, no shock at all. Would that there were YouTube of this, it would have looked hilarious.
The makeshift double pole was by then separating and starting to tear itself apart from this lateral force. Not quite, but it started. I could just take it the rest of the way apart but something tells me I should reassemble and reinforce it for, you know...
He got good and drenched last night in a torrential downpour. Now he's scoping out soft places to sleep. Perchance to dream. Now that that's done I can go get acquainted with my new chainsaw.
