We have 4 cats that live inside w/ us. Since we aren't home 'cept in the evenings our cat boxes go several hours w/out being cleaned out. Petra, our oldest cat, is picky about who she shares a cat box with and has taken to using the floor outside and around the box. This spring while it was nice outside we left the door open to the screened in porch and put the box out there. We also allowed the cats to sleep out there (not by choice, they just didn't want to come in). To our surprise, Petra would use the box just fine when it was out there. My guess is that it has something to do with ventilation. The "aroma" of the other cats having used the cat box must have dissipated enough for Petra to be content enough to use it. Our next step is to put a cat door in the door that leads out to the screened in porch. The only problem is that I'm not sure how to install a cat door in the kind of door we have (see pic below). Can this be done, or should we pick up a new door?
BTWetra is a big cat, so the cat door will have to be somewhat low for her to actually use it.
