Due to neighbours extending their houses on all sides of us, our cat's route to the woods across the (quiet) road is blocked and we have taken to leaving a downstairs window open for him.
Obviously this is only possible when we are around and in warmer weather so we need to install another cat flap. The only realistic site is in the steel up-and-over garage door. We want to use a chip secured flap.
Has any one put a cat flap in their garage door of this type? Would the steel surround affect the chip reader? Any ideas gratefully received.
