Aloha personaobscura. So nice to here that you don't have anything against cats and that you're a previous owner of them. I'd be happy to give you a tour of our sanctuary and answer any of your questions.  I think if you see our place, you'd be surprised on the fence design and may even change your mind about the cats getting out. We bring in on average of 150 cats a year and every cat is vaccinated, microchipped, spayed or neutered. Our population is just under 500 cats (and growing) in a 25,000Sq.Ft. open air enclosure. If they are all getting out, they must be leave in the middle of the night and all sneak back in before we get there at 6:30am. lol Learn more about us at lanaicatsanctuary.org ~aloha
