CEESC Medium Cat Door for Interior/Exterior, for Pets <15.75"

• ROTARY 4-WAY LOCK:​ The knob-style switch is 4-way rotary. Easily rotate to 4 modes - In Only, Out Only, In & Out Freely, or Fully Locked - to control your cat's access with one hand.
• MEDIUM (M) SIZE – MEASURE BEFORE ORDERING:​ Inner passage: 6.18"W × 6.30"H. For cats with waist circumference <15.75" (typically under 11 lbs). Outer frame: 7.5"W × 8.46"H. Please measure your cat's waist circumference and your door thickness before ordering. If your cat exceeds these limits, choose our Large (L) size.
• UPGRADED WEATHERPROOF BRUSH STRIP:​ Fixed groove with snap tabs firmly secures the brush strip. Greatly reduces noise, blocks wind and rain, and keeps out drafts. Even if the brush strip comes off, it is easy to put back into the fixed groove.
• ADJUSTABLE TUNNEL DEPTH:​ Tunnel depth fits doors 1.26"–2.14" (32–54mm) thick. Can be trimmed according to your door thickness for a snug, secure fit on interior or exterior doors.
• COMPLETE INSTALLATION KIT:​ Includes 16 screws (8 long + 8 short) and step-by-step instruction manual. Refer to the installation video on the product page for visual guidance. Screw from both sides of the door to prevent cracking - do not screw from one side only.
