My entire house is decorated with my pets in mind, and I'll go even further to say that when we bought this house, it was with the needs of our babies in mind.
I have too many different colors of critters, so I could never settle on a furniture cover that would hide all of the fur. The last sofa I went darker than normal, as the black hair from my dog and 3 of the cats tended to make lighter color fabrics look dingy. But I have blankets that match the theme of the living room covering the sofa, love seat and chair.
Cat trees are either neutral colors, or made from carpet remnants that match the room. I've gone down the path of bamboo and rattan on some furniture cause it matches the sisal on the scratch posts (which are strategically placed next to the furniture they might be tempted to scratch).
Since I make my cat beds, they also at least match the general color themes in my house.
I'm about to paint my sun porch and as I'm deciding color, I look at the 3 cat condos in that room. One is dark brown, one tan and the other cream. You canl bet that the room will end up painted in a color that will compliment the trees.
I'm in the process of remodeling my kitchen. The window sills are wide enough for cats and low enough for the dogs to look out. Blinds are cordless so they can't hurt themselves, and the bar counter we added is now affectionately called the "cat walk". The floor was chosen to specifically hide not only hair, but muddy footprints from the dogs (it's working).
A bathroom is also under remodel and the tile was chosen to hide pet messes (litter box in there also). We added a near silent venting fan to suck out the smell of the litter box.
Utility room remodel: added the silent venting fan (another litter box area), a large counter for another feeding platform and specifically had an electrical outlet strategically placed so that I could plug in their water fountain. Added a huge window over the counter so that cats could look out as they nibbled.
Another bathroom has a great vanity counter that makes the perfect feeding platform for the cats. When we get around to gutting that room (it still has the original 1972 harvest gold and brown marble), that counter will be replaced, but still remain for their needs.
Drapes: machine washable or I don't buy them.
Then there are the general things I do through-out my house to protect my cats from hurting either themselves or my belongings.
I don't own an open book case or cabinet. Every small item that could get knocked over or broke is safely housed in a china cabinet, curio cabinet, or glass doored case (books, CD's, TV cabinet). Even my computer is in an armoir.
Kitchen and bathroom cabinets have interior latches or strong magnets on the ones that hold chemicals. All garbage cans have lids.
So yeah, I guess I decorate with the cats & dogs in mind.......
