I know how much your animals mean to you. I have 3 cats, a dog, horse, and a 5,000 gallon water garden loaded with koi and other fish; they are all my children and a part of me, and often their needs come first. I once saw a small sign on an entry door which sums it all up with a smile:
"This house is maintained for the comfort and security of my pets. If you cannot accept that, then you cannot accept me, so go away."
Again, best of luck in this endeavor, and we'd appreciate news of your progress. It's a wonderful idea.
