http://www.sacpaws.com/home/Blog/Barb111/348 Jon Jon and Percy have always enjoyed their outside time anywhere between 6 and 8. But now JonJon wants to stay out when its dark . He tells me its the best hunting time. I have been working on the patio sometimes into the dark and Jon loves it he plays Kommando Kitty. He ducks in the grass, like no one can see him, ears flat, and then POUNCE!!! He has landed his bug!!! But it grosses me out and I just don't think its a good idea for him to be eating bugs. My partner says I am overprotective but I disagree. Anyways I also wonder about the mosquitos. I have heard they can hurt animals too so I really try to watch if the mosquitos start up and if they do I put him in but then I have to come in lol because he just stares at me from the sliding glass door and I can't bear it so I end up coming in too. I'm not over protective but maybe I spoil them---just a little. lol Jon Jon and Percy have always enjoyed their outside time anywhere between 6 and 8. But now JonJon wants to stay out when its dark .

Let them have their fun!!!  You're lucky you don't live out in the country (like me).  We don't have cats anymore, but our neighbors with cats have to worry about a family of foxes and coyotes out here!
