DH says our cats are so spoiled, they don't even know they're spoiled. They think all cats live like this.
They only drink bottled water (we had issues with our well when we first moved in, went to bottled water and, even though we now have a water filtration/osmosis/softener system in the basement, they still drink only bottled water).
I wash all of their blankies, pillowcoverings, towels, etc. every week, so they're always clean and fresh for them. It is one full load of laundry because there are lots of blankies and pillows throughout the house.
In the winter, we keep our house fairly cool. When we're home during the day, the electric blanket on the bed is never turned off. And as soon as we come home from work, the very first thing we do is go to the bedroom, plug the blanket in, and set both sides. That way, when they're finished with supper, they can go to bed in comfort. (And if, by some chance, we forget to turn the blanket on? BooBoo will come to use and start meowing to remind us that we forgot! He'll meow and then look back the hallway. That's my cue to get back there and turn that blanket on for them!)
I had put a small pillow on my desk in the computer room for Banshee, our Bridge baby, because she was always with me. After we got Mollipop and she decided to hang out with me, we put the pillow back on my desk for her. It's now called "Mollipop's Throne" and she likes being there when I'm on the computer. My desk is huge and there's plenty of room for my stuff and her stuff, too.
They have their own kitty couch and they do use it. They have their little toy box, shaped like a mouse, and BooBoo will peek his head inside the toy box, pick out a toy, grab it with his mouth and pull it out to play with it.
Years ago, when Ms. Pepe was younger, she loved to lay on top of the refrigerator. I figured she might as well be comfortable there, so I bought a large dog bed and plopped it on the fridge, so that when she jumped up, she could lay in comfort. She loved being on top of her world and it was funny to see her head sticking out looking at us when we opened the fridge door. The pillow is now on the bedroom floor b/c Pepe has a hard time jumping that far since she's gotten older. (A note of caution: If you put a large pillow on top of your fridge, make sure there's still enough room for air to circulate around the fridge coils and such. I was always moving that pillow to the front of the fridge.)
The cats are afraid of the vacuum cleaner, so right before I vacuum, we have catnip parties. I'll put a small amount of catnip in six little piles on the living room floor. The cats will each go to a pile, eat, sniff, roll around, get high and act goofy. Then they get a nice snack and I'll carry each cat back to bed. I'll close the door and they get a nap while I'm vacuuming the rest of the house. I'll wait until they awaken again and after they're moving around, then I'll go into the bedroom to vacuum and clean. (Our main catnip parties are usually on Saturday morning. DH does banking and such and while he's gone, I'll do the main vacuuming and clean the house a bit.)
Whenever I make something with canned tuna, I open one extra can. That can is divided up amongst the six cats....Mollipop has decided that tuna is a very good thing. I've done that for years. I don't know what I'm going to do if Tabitha decides she likes tuna, too. They don't get much, it's just a smidgen, but they really enjoy it.
We buy Frosty Paws for the cats...it's basically a kind of ice cream for your cats...they have it for dogs, too. I'll take a small package out of the container and divide it for the six of them. They all love it.
You get the idea.

It's our cats' life; we're just here to open cans. And it's our cats' house; we just pay the mortgage.
