I have had the same issues when it comes to vet visits. They come home smelling different and it sends all the warning signals out! I have worked through this by keeping the kitty that visited the vet away from the others for a while. I have a spare bedroom that Huck recovered in so I had full control over who came and went (and when). 
  

Thanks paws120! Unfortunately the spaces in our apartment are pretty limited, especially with the dog kennel set up we have rigged. The living room is the one spot that it will fit, and we can't give her free reign of an entire room, because she WILL try jumping and hiding ASAP. Plus in the living room, my roommates can stop and give her love, and she gets to see what's going on. 

The vet did recommend that when I do start letting her out on a permanent basis, I give the monkeybutt some gabapentin to keep him calmer and hopefully from knocking her down... *facepalm

For your purposes it might work well. I had Huck in a big deluxe doggie crate in his spare room. I actually agree with you on the getting attention part (with everybody having access to Raz), and I am wondering if in a few more days they might just get back to their normal selves anyways. Do you have any Feliway spray? I have both, and I used the diffuser plugged in pretty closely to where I had my crate. I selectively spray different areas to help that work. Like a rug or towel in front of the crate so that Kho might cool his jets a little. I use it on all of my cat trees when they are not occupied. Cats are such unique individuals. He probably doesn't understand the crate, and may also be a little jealous of the extra attention that Raz is getting, and the whole surgical site/cone probably doesn't help either.

  

Kho was really sweet for her two weeks when she was in the crates pre-surgery. He would come check on her, sleep on top of her. He was the best protective brother. Now, he's crazy...I need to get a little more cat food tonight, maybe I'll pick up the Feliway spray and see how he reacts to that. He gets SO MUCH love, silly boy. I took Raz out on a leash tonight to walk around, praising her for every little thing, and he was giving his best "not impressed" stare. 

How is the recovery going? Please make sure she gets enough fluids, I cannot even stress that enough. Be it through canned food, broth, roasted chicken, tuna juice... all of the above. With the anesthesia and different meds it can bind them up big time and a dehydrated kitty is very dangerous. You will be able to gauge some of that from urine output. Her appetite may drop too, that's why I had all the good stinky treats for Huck. It happens a lot usually somewhere around day 4ish. It will get better though, just baby the heck out of her and make sure she is drinking and eating.   

So far it's going really well! It's only been two days since surgery and she is already more herself than she was before! She is eating really well today AND SHE JUST POOPED!!! I'm a proud meowther. I tried putting some dried food out, but I think I'll remove it and we'll stick with the wet food for now. I'll keep an eye out this weekend for the drop, thanks for the warning!
