Don't you have anyone in your area that installs doggie
doors? It is usually best if you are dealing with a complex
situation to leave it to a professional. I do also agree
though that the little ones are too small to be left out
doors unattended. Predator animals aren't the only danger
there are also predator people and then the chance of
them getting out and getting lost before you even realize
they are gone scares the heck out of me but thats JMO.
