When he returned and decided it was okay to stay around for mealtime, as I got closer to him, it was obvious he had an eye problem. He didn't seem painful with it, so with time and kitty tuna, we became friends & I was able to catch him for an exam. At some point in his adventures, he sustained a puncture to his eye, a nasty wound which caused the eye to shrivel up and scar over time. Ouch!
Blind in one eye, Sylvester spends his days pretty close to home now; his primary job is that of mouser, as we don't use rodent bait (or any pesticides) on the property. He also helps with watering plants and feeding the other animals too. As he gets older and slows down, he may even settle down enough to live with the Cabana kitties!
