For ChubbyKat/HeftyKat/Med.Pet Flap/Solid LEXAN™ Plastic Flap/Plastic Frame/Chrome Steel/4-Way Lock - 3 Pcs.
To determine the correct size door, simply measure the width (A) and height (B) of your pet.
(A) Measure the widest point of your pet's shoulder.
(B) Measure from the top of your pet's back (just behind their head) to the bottom of chest.
Pet door models have different size openings. Just make sure your new pet door's opening is both wider and taller than your pet's measurements to ensure they can comfortably pass through.
My old one was worn out and one of the cats learned to move the lever to “open”. The lever on the other door is still tight so I have only the one to replace so far. It’s Great the parts are available. Thank you for offering them
Got my pet panel several years ago. The switch on the cat flap was failing. It kept slipping, locking the kitties out. Tried replacing this part, now it holds perfectly.
