Door Buddy Door Prop for Cats — Adjustable 3–5.5" Gap, Renter-Friendly Strike Plate Replacement

Door Buddy Door Prop for Cats is an adjustable, non-permanent interior door latch holder that keeps a door cracked open for cats while preventing larger dogs from entering.

This compact, American-made strike plate replacement gives you a safe, simple way to create a 3–5.5 inch gap for pets without cutting holes or installing bulky gates. Designed to fit standard interior doors, the Door Buddy installs quickly using your door's existing holes and stays in place for everyday use, travel, or rentals. It's built from durable materials so it resists prying and movement when propped, keeping fingers and tails pinch-free.

How does this let my cat in while keeping dogs out?

The Door Buddy replaces your door's strike plate and locks the latch in a partially-open position sized to your pets. You set the opening width so cats can slip through but larger dogs cannot. It works whether the door swings left or right and with common interior door thicknesses.

• Adjustable opening between 3 and 5.5 inches for precise fit
• Replaces existing strike plate using original screw holes
• Works with standard interior doors 1-3/8" thick
• No adhesives, cutting, or permanent modification required

What installation steps are required and is it renter-friendly?

Installation is straightforward: remove your current strike plate, attach the Door Buddy using the same screws, adjust the width, and tighten. No new holes, glues, or door cutting are needed, so the unit is removable and suitable for renters and travelers.

• Uses existing screw holes—no new drilling
• Includes T8 Torx tool for width adjustments
• Removable and reusable for temporary setups

Will it stand up to determined dogs and avoid pinching?

Door Buddy is made from thick, high-quality parts that resist movement when latched, so it holds the door firmly in the propped position. The design eliminates shifting that can pinch fingers, paws, or tails and prevents pets from accidentally closing the door on themselves.

• Robust materials for long-lasting performance
• Secure latch engagement prevents wobble or slippage
• No exposed moving parts that could pinch pets or people

Which doors and situations is it NOT suitable for?

The Door Buddy is optimized for standard interior doors and strike plates; it is not compatible with thicker exterior doors, pocket doors, barn doors, or oversized frames. Measure your screw hole spread and door thickness before ordering to avoid fit issues.

• Compatible with standard strike plates with screw holes 1-5/8" apart
• Fits interior doors 1-3/8" thick only
• Not for exterior, pocket, barn, accordion, or wide/extended frames

Who is this for: Door Buddy is ideal for cat owners who want an easy, reversible way to give indoor cats private access to feeding or litter areas while keeping larger dogs out. It's also a good choice for renters, frequent travelers, multi-pet households, and anyone who prefers a tidy, non-destructive solution over pet doors, gate systems, or permanent door modifications.
