Direct answer: If a cat tore the screen but the screen door frame is still straight and the spline channel is intact, this is usually a screen mesh repair, not a whole door problem. Start by checking whether the tear is small enough for a temporary patch or whether the full screen panel needs to be re-screened.
Most likely: Most of the time, the mesh is shredded near the lower half of the door while the frame itself is fine. The next most common issue is a bent screen frame edge or damaged spline groove that will not hold new mesh tight.
Look closely before you touch anything. A clean tear in the mesh is a different job than a pulled-out spline, a bent frame corner, or claw damage that loosened the door in the opening. Reality check: most pet damage looks worse than it is. Common wrong move: patching a screen that is already loose all the way around.
Don’t start with: Do not start by buying a whole screen door or smearing glue across the tear. That usually leaves a weak, ugly repair and still does not fix loose mesh.
A hole or short rip, usually near the bottom, while the rest of the screen still looks tight and flat.
Start here: Check whether the mesh around the tear is still firmly held in the spline channel. If it is, a temporary patch can buy time.
The mesh is ripped across a wide area, with strands hanging loose or missing.
Start here: Skip patching and inspect the full perimeter for loose spline or stretched screen. This usually needs full screen mesh replacement.
The mesh is detached along one side or corner, sometimes with the rubber spline sticking out.
Start here: Inspect the spline and the groove in the screen door frame. If the groove is intact, re-screening is usually the right fix.
One corner is twisted, the screen panel will not sit flat, or the door rubs after the damage.
Start here: Check the frame rails and corners before replacing mesh. New screen will not stay tight in a bent screen door frame.
This is the most common outcome when a cat climbs or pushes through the lower section. The frame stays fine, but the mesh is cut, stretched, or shredded.
Quick check: Press lightly around the tear. If the surrounding mesh is still snug and the frame edge is straight, the damage is mostly in the mesh.
A hard push can yank the mesh from the channel, especially at a corner or along the latch side.
Quick check: Look for a rubber cord sitting proud of the frame or a screen edge that has slipped out of the groove.
Even if the tear is only in one area, repeated clawing can leave the whole panel baggy and wavy.
Quick check: Sight across the screen in daylight. If it sags, wrinkles, or bellies out, patching will not hold up well.
If the pet hit the lower panel hard or the door was kicked afterward, the insert or outer frame can rack just enough to keep new mesh from tightening evenly.
Quick check: Open the door and compare the frame edges. A bowed rail, twisted corner, or gap that changes from top to bottom points to frame damage.
You want to separate a simple re-screen job from a door alignment or frame repair before spending time on the wrong fix.
Next move: If the frame is straight and the damage is only in the mesh, stay on the screen repair path. If the frame is bent, the insert is twisted, or the door no longer hangs right, the job is bigger than mesh alone.
What to conclude: Most homeowners find the door frame is fine and only the screen panel needs attention. If the frame is out of shape, new mesh alone will not stay neat or tight.
A patch is fine for a small isolated hole, but it is a waste of time on stretched or loose screen.
Next move: If the damage is small and the rest of the screen is solid, a patch can get you by until you re-screen the panel properly. If the mesh is loose, brittle, or torn in more than one place, skip the patch and replace the full panel screen.
What to conclude: Small clean damage can be patched, but widespread pet wear means the screen has already lost strength.
A new screen will only stay put if the screen door spline channel still holds properly.
Next move: If the groove is clean and intact, a standard re-screen with fresh mesh and spline is usually straightforward. If the groove is split, badly deformed, or the corners are broken, the screen insert or door frame may need repair or replacement instead of just new mesh.
Once you know whether the panel is patchable or needs full replacement, you can make a repair that actually lasts.
Next move: If the screen sits flat, tight, and even with no pulled corners, the repair path was correct. If the mesh puckers badly, pulls loose, or will not tension evenly, stop and re-check for a bent frame, wrong spline size, or damaged groove.
You want to know whether you are done or whether pet damage also loosened the door hardware or frame.
A good result: If the panel stays tight and the door operates normally, the repair is complete.
If not: If the screen is fixed but the door still hangs poorly or the frame is damaged, move to door hardware or frame repair rather than redoing the screen again.
What to conclude: A good screen repair should survive normal opening, closing, and light contact. If operation is still off, there is a separate door issue to address.

Yes, but only if the tear is small and the rest of the screen is still tight and sound. If the panel is loose, brittle, or ripped in more than one place, full screen replacement is the better repair.
If the old screen door spline is cracked, flattened, hardened, missing in spots, or will not stay seated when you reinstall the screen, replace it. Old spline is a common reason a new screen comes loose again.
Usually the frame is slightly bent, the mesh is being pulled unevenly, or the spline size is wrong for the groove. Stop and correct that first instead of forcing the screen tighter.
Not usually. Most pet damage is limited to the screen mesh and sometimes the spline. Whole door replacement makes sense only if the screen door frame is bent, cracked, or no longer operates properly.
Treat that as a separate door problem. Fix the screen, then check hinges, mounting screws, and frame alignment. If the door frame itself is damaged or loose in the opening, address that before redoing the screen again.
