I am considering putting a doggy door on my back door but it is a paneled door and I'm not certain if putting one in is even possible. Has anyone tried this? If so, did it work and could someone who has some home improvement skills but who is not in any way an expert do this?
Also, is it even worth it? My two big concerns is that living in Houston there are a lot of bugs (cockroaches, mosquitos, etc.) that can get in even the smallest of openings and I am worried that a doggy door might be an open invitation for them to come in. Also living in Houston, the air conditioner is on almost 365 days a year. Does the doggy door act as a big crack causing all the cool air to be 'let outside' and increasing air conditioning costs?
