Main Entrance Dilemma

[myfs_102704]

Okay, I'm JUST getting into learning about Feng Shui and I have a question.fficeffice" />

In my house we do not use our front door. There are two reasons for this:

1) I have indoor cats and it would be all to easy for them to bolt out the front door when it's opened.

2) If the front door isn't locked it can blow open very easily and again, we risk losing the cats (never mind the potential for theft and such).

So what we've done is we just leave it looked (unless someone comes to the front door such as the mail man and such) and instead use the back door for the daily comings and goings. This works well since we can make an air lock out of the computer room (which the back door leading into) and keep any determined kitties form escaping.

However, I'm now wondering how this is affecting the chi movement in my house. Is the above situation problematic? and if so, how and what do I do to address it?
