Maybe "CLEAR PROP!" doesn't translate well into feline?Interesting to be able to tame a totally wild animal...he appeared with one ear chewed off, probably in a fight, or perhaps something a coyote did to him.
I commend you for looking out for the cat (even if it is a "you scratch my back..." arrangement). The 'doggy door' idea is a great one that not a lot of folks would think of doing.about two years ago as i was starting my second rv a ferral cat appeared...i just happened to have some dry cat food, so i kept putting that out in a bowl by the hangar door every night. After a very long time the cat would come into the hangar to get food and water...months later i was able to touch him, although he would swat at me quite often. By now he has become a lap kitty and sleeps in the hangar way up in a storage cabinet on a folded up quilt. When it is cold, as over winter, there is a heat lamp for him. I also added a 'doggy door' so he can come and go as he wishes. He is now a permanent resident in the hangar.
