Pet proof window screens are now possible using heavy duty fiberglas tough door screen material.
This material was originally used as a luggage container fabric but was found to be exceptionally resistant to pets scratching on the patio door screen to get in and get out.
It might be advisable to have a glass shop install this material for you because it does require the right spline size, and is more difficult to roll in than ordinary screen fabric.
If you are careful, it is not an impossible project for a do-it-yourselfer to accomplish. Just be sure to get the right spline size for your patio door.
Most likely the spline size that you remove from the door will be too large to reuse with petscreen. You will probably have to go down one or two sizes to roll the new petscreen in place.
With petscreen its best to preroll the material into the spline groove before you roll the spline in. Its also essential that you clamp the screen cloth on the patio screen door before starting to roll, that way you can assure that it goes in square and true.

You can install various types of "scratch" protectors over top of your screen door or storm door, to guard against pets who claw to get in. The difficulty is, these items only protect one side of the door, and screen doors dont have clearance on the inside to install one without preventing the door from sliding.
Before petscreen came along, I would sometimes install plexiglass in the lower half of a patio screen door. This works if the screen door can support the added weight of the plexiglass.
