Regarding the video "Save the birds, keep you cat safe" the author requests that cat owners keep cats inside for birds and cat safety. I agree whole heartedly but don't know how it is possible. These are avid hunters and my cat sits in wait until the door comes open a crack and then darts out. I have three children with friends and family coming over. First chance and my cat will get out. She has even clawed or chewed her way through my window screens. So how do I get fresh air in my house and still keep my cat indoors. I get so frustrated because it sounds so easy to just say keep your cat inside. Not possible though. Suggestions?!
