I arrived a few hours later and easily found the cat exactly where Carl had told me. He was a pretty orange tabby, and, when I walked beneath him and talked to him, he cried down to me and appeared to be a friendly kitty. He was only 15 feet high but about six feet out on a long limb of this Tallow tree.
As we went down, he suddenly became very nervous, and I suddenly realized I had made a big mistake. Anytime I rescue an unknown cat, I always like to contain them, ideally in the cat bag, so I can scan them for a microchip, but this kitty was not contained, and he was now too nervous to hang around once on the ground. Shortly before reaching the ground, he jumped from my lap to the ground and trotted away a short distance where he stopped to look back at me. He continued to trot away and stop to look until he went under a nearby house.
I still had hope that he would calm down as before and come back out to see me as long as I remained unthreatening. I calmly packed up my gear, and, when I had finished, I looked for the kitty and tried to entice him out to me again. I could not see him, and he was not coming back out, so, after several minutes, I gave up and left. He was clearly a tame and loved boy, and the chances are very good that he went back to his home nearby, but this is one time I had to leave without knowing that for sure.
