You may want to just keep the sliders and add screens if you want the cats to stay inside. I have Pella sliders with a screen that's on the interior side of the sliding door and I consider it perfect for use with pets. It can be latched/locked so there's no chance my cat can get outside. Since your cats are indoor/outdoor now, consider doing what holly mentioned. My cat has a cat door in the BR that opens to a wire tunnel. The tunnel then leads to a 10', six ft. high kennel that sits in the corner of the deck. Makes for a happy cat..........

On the sliding screen door for my older patio door I need to replace the fiberglass screen. The first step however is to remove the old fiberlass screening which seems to be (nicely) held in place by a thin bead of adhesive/caulking applied in the groove where the spline would normally be. Once I get the adhesive out I imagine they'll be no problem installing a new screen using new splinbe in the groove as usual. I hope/assume I can just peel the old adhesive out by poking in the groove and the pulling the old screen out etc. Any one have some advice - want to make sure I can do this properly before I start ripping the old screen out. Many thanks.

I know I'm late to the conversation here but I just wanted to follow up in case anyone else had the same question. Retractable screens are just as durable as fixed screens but much more pleasing to look at. A quality retractable screen, like the Plisse by Screen Solutions inc, should come with a lifetime warranty that provides peace of mind when investing the associated money into your home. Check out www.plissescreen.com and see for yourself why retractable screens, and in particular the Plisse retractable screen, are a better choice than traditional fixed screens.
