The process of installing a cat flap may be a bit daunting but it's simple with the proper instructions. Determine how high you would like your cat flap to be (normally it's located at the belly height). Then, mark this area on the door and then use the template provided as a guide to drill. If you have a kitten who is still a baby then gently prop the door slightly open and allow it to pass through. Reward it when it goes through. Meas
