I need to install a cat door for one of my garages ( the 5 cats home ) I currently have a small cat sized cut out covered by a cloth flap which works well BUT it also allows unwanted visitors in . I was thinking maybe some one here has had experience with RF-ID tags (Radio-frequency identification) in cat collars .

I had a Staywell magnetic cat flap. It worked OK but needed careful adjustment. But some cat flaps just aren't well made:

Even IR flaps aren't totally secure:

But, as it is warm enough in Phuket, the little devils can sleep outside:
