I have an F3 and two Ragdolls in a townhouse. In their townhouse, sorry, my mistake. My Duma is the perfect gentleman. He has never broken anything, had any accident, or scared anyone by being too forward or too demanding. Sometimes I wonder if he's really a SV. He's not that big, but he does have huge ears and a slender body, which make it obvious he's not a normal cat to anyone who sees him. He's always trying to make friends with big brother Dante, and occasionally he breaks through; he and Desi seem to be great buddies, although Desi is less mobile than Duma and that seems to frustrate both of them. When I take out Da Bird or Neko Flies, Duma gets first play, but he is such a gentleman that when he sees a ragdoll jump for the toy he'll stand back and let them play for a while. I had no idea that cats would do that for each other! Same with boxes, Dante loves boxes so Duma will wait his turn. Well, maybe it's because if either Duma or Desi is in the box, Dante will sit on top to claim the box.
Dante is very moody and picks on the other two a lot, but despite this, I've caught massive three-way grooming sessions on video. So I know they don't *completely* hate each other, but I do think that Dante hates everyone and everything from time to time.
I have two litterboxes upstairs, both Clevercat boxes, and two downstairs, one Cat Genie and a regular hooded box. Typically the one that gets used is the one in the bathroom I'm in, as we're group pee-ers in this house. Only Duma seems to use the Cat Genie, I think my big Ragdoll 20+ lbs is too big for it and Dante who is under 12lbs is too picky to use it.
The three eat in the kitchen. Duma likes to eat on the counter before everyone's been served, sometimes before it even hits his dish. Desi has a mat on the floor and Dante sits on a ladder I keep in the kitchen. Although sometimes I give Dante alone-time in the downstairs bathroom with his meal. There's a ceramic fountain in the kitchen but I rarely see it touched. Food is commercial raw, home-prepared cooked, or occasionally cans. Rotated frequently because they tend to get bored.
All of my furniture is some form of leather or vinyl. Desi excretes tumblin' Desi-weeds all over everything (ironic since I promised I'd never ever get a long-haired cat), so I can't have anything but leather. Like Deborah's, my sofas have marks and faded spots; one of the sofas is Dante's 2nd favorite place to pee when he wants to punish me for some perceived wrong, such as not letting him roam on his own outside all day. The other has micro-toenail marks all over it from them playing on it. I've given up on having good furniture and just concentrate on furniture that doesn't smell. Nobody notices the marks anyway.
I have a good-sized fenced in backyard and garden but they figured out how to get out, so I don't let them back there anymore

I tried putting them out there on leads but it just doesn't work. I've been building a cat cage but as the weather has turned cold and I've been away for work I haven't really had the time to work on it. Duma goes for walks on his leash with me on the weekend, though, so he still gets some outside time.
My office has 3 cat trees in it, 2 of which are floor to ceiling. I had started a project of extending the trees so Duma could literally run the ceiling, but then I thought I was moving so never finished. At some point I will finish this project too.
We all fit on the bed just fine. Dante is always in the furthest corner, just out of reach of everyone--and I think he is responsible for kicking Desi out of the bed, on the few nights Desi has spent the night in the bed Dante slept elsewhere. Duma is always on my legs. It's clear it's his spot. He took it up after he was neutered and never changed. Before that he was my snuggle buddy, so I'm hoping as he gets older he might come back to prime snuggle position (he hits 2 in January). Meanwhile Desi fills that spot intermittently, I think he gets too hot to snuggle for very long.
I think Duma really wants a SV brother. A few nights over the last few months I've had the strangest dream, that Duma was telling me his ears were too big and he wanted to cut them off--eeeek! Maybe it's him trying to tell me that the Ragdolls don't look like him with their little ears. I keep telling him his ears are beautiful but he won't listen. I would really love to get him an F2 (or F1, but I doubt I could afford one) that he could play with, but I don't know that I could handle taking care of four cats. Three is a lot. How did I even end up with three? It's a lot of

to scoop.
