I'm back! I hope you've all enjoyed Geoff's updates in my absence.
As Geoff mentioned earlier, Melly went to the vet this afternoon. Naturally, she charmed everyone there with her rambunctious antics and all-around adorableness. (The fact that Sue is beloved at the vet's office didn't hurt either :) Aside from a possible cold - she sneezes a lot - Melly's healthy, weighing in at 2.7 pounds. This surprised the vet tech, who said Melly had way more than 2.7 pounds of personality. Melly also got a vaccine, which was thoroughly unpleasant, and which has made her a bit lethargic.
At Tanya's suggestion, I've added a second litter box with a different kind of litter in the bathroom. Melly has already used it; if she continues to do so, I'll take out the old litter box. Geoff also got Melly a scratching post, which she uses both for its intended purpose and to sleep on. And, in the interest of attempting the bedding exchange again, I've added a folded up towel next to the scratching post. Last I saw Melly, she was curled up on it, snoozing. As you can imagine, the bathroom is getting pretty cluttered!
Scarlett's food has been relocated to just outside the door of the bathroom. She adapted to this fairly quickly, which isn't terribly surprising since Scarlett is a great lover of all things edible.
She seemed to hope that the arrangement was temporary, though, since she went back to where her food normally goes and mewed expectantly.
After this, Geoff took a piece of chicken to feed to Melly and I took one to feed to Scarlett. We sat on opposite sides of the bathroom door and fed bits of the chicken to the kitties. Geoff said that Melly didn't react to Scarlett's presence on the other side of the door and concentrated solely on nibbling her treats. Scarlett was very much aware of Melly, but was too distracted by the chicken to bother with tail lashing or anything of the like. After the chicken ran out, though, she sniffed under the door and let out quite a growl. Since then she's been a bit angsty, and even went so far as to swat at Geoff a few times when he tried to pet her. (He would like me to note that he managed to avoid injury due to his super-cat-like reflexes.) Scarlett remains friendly toward me, possibly because I currently have less of Melly's scent on me.
My plan is to continue the current routine of letting Melly out occasionally while Scarlett is confined, and leaving Scarlett's food by the bathroom door. We'll keep doing the simultaneous chicken feeding, and I will give the bedding exchange another try in a few days after the cats have a chance to get their scents on the newly-washed towels. This transition is much easier now that there's an established routine in place!
