Overview
A sliding glass panel insert from Dreampedal built to replace a section of a sliding patio door, giving cats and small to medium dogs their own weatherproof, lockable pass-through without cutting into the door itself.
Despite the category listing it under cat doors, the spec data lists both cats and dogs as the intended pet type, with a 40-pound weight capacity that covers more than most cats. It fits sliding patio door openings between 76.38 and 81.1 inches tall, and the aluminum frame with a lockable panel is meant to seal the opening when the pet door is not in use. This is an insert rather than a door cut, so it works only where a sliding glass door already exists.
- Adjustable height range 76.38 to 81.1 inches
- Aluminum frame, sliding lock closure
- Weight capacity up to 40 pounds
- Rated for cats and dogs, medium size
Who it's for
Households with a sliding patio door who want a cat or small to medium dog to come and go without a permanent cut in the glass, and whose door opening falls in the 76.38 to 81.1 inch height range. Not suited to swinging or French doors, or openings outside that height window.
Strengths and trade-offs
Drawn from this product's published specifications.
- Fits sliding patio doors without cutting glass
- Lockable panel seals the opening when not in use
- Rated for pets up to 40 pounds
- Only fits doors in the 76.38 to 81.1 inch height range
- No seller description or reviews yet to confirm installation ease
Performance notes
The panel slides into the track alongside the existing glass door and locks in place, with a sliding lock on the pet opening itself so it can be sealed off when needed. The aluminum frame is built to handle outdoor weather exposure, and the 40-pound capacity means it can serve larger cats and medium dogs, not just small pets.
