How-to
My cat won't use the cat flap — how do I train it?
Break it into tiny, rewarded steps: prop the flap fully open first so it's just a hole, lure the cat through with treats from both sides, then lower the flap gradually so the cat learns to push. Force-free and patient — reward every success, never push the cat through.Fact
Cats learn well with positive reinforcement. The flap is scary because it touches them and blocks the view; removing those one at a time is the trick.
Applies to: Owners installing or troubleshooting a cat flap. (Outdoor access itself is a separate safety decision — see related.)
Steps
The step-by-stepFact
- Stage 1: tape/prop the flap fully OPEN so it's just an opening; lure through with treats from both sides
- Stage 2: let the flap rest lower so the cat brushes it; reward pushing through
- Stage 3: full flap — reward the first pushes, then fade the treats
- Keep sessions short and always end on a success
Make it positiveProfessional guidance
- Mark-and-reward each success (clicker or a consistent word)
- Never shove the cat through — one bad experience sets you back
- Let the cat approach on its own; two people (one each side) helps
Practical notesProfessional guidance
- A see-through flap is less scary than an opaque one
- Microchip-activated flaps keep other animals out (a category, not a brand endorsement)
- Decide the OUTDOOR-access question first (see the safety page) before free flap access
Normal vs keep-watching
Normal: A cat that pushes through the flap confidently after gradual training.
Keep watching: Which stage the cat gets stuck at (usually the flap touching them), and whether treats are rewarding progress.
When to contact a vet. Not medical — but if outdoor access is involved, review the safety trade-offs and ensure microchip/ID first (see related).
What changes this answer
- Opaque vs clear flap (clear is easier)
- Indoor-only flap (room access) vs outdoor
- Nervous cat (slower stages)
Common mistakes
- Starting with the full closed flap
- Pushing the cat through
- Long frustrating sessions
- Free outdoor flap access without the safety decision
