We live in western Washington in the US (winter low temperatures are usually above freezing, rarely in the teens). I'm thinking about putting in a pet door for three animals: a largish cat (about 12 pounds and quite agile), a middle aged toy poodle, and a young standard poodle.
I'd been leaning towards the through wall model of the Patio Pacific Endure Pet Door in a size 10 (10" x 18" flap) until I read some reviews which said that cats and small dogs have problems with these doors. It sounds like the closure that seals the door well also makes it difficult for small animals to open.
Am I likely to be able to find a door that will accommodate all three animals? Even though we don't have severe winter weather, previous doors have gotten unpleasantly drafty over time.
