Since stopping the antihistamine, the wailing has practically ceased. I can't take them either; I get so jittery that I cry and at times feel like I want to scream so she probably just does scream. She slept almost all day yesterday, so she got plenty of rest. I was worried that she might be up all night (memories of Puddy and her nocturnalism) but she did ok. She got up to use the litterbox and ate but not excessively. At one point, I waited for her to come back to bed and she didn't, so I went looking for her and found her standing behind the recliner in the living room. I have a cat scratcher there but I didn't hear her using it. Then she walked over to the basement door and started meowing but I didn't want to let her in there because I wanted to keep an eye on her and I also didn't want her to wake the Fur Posse, so I carried her back upstairs and she used the litterbox again. One thing that she's doing now, though, is pooping just outside the box. If I can, I'm going to try to catch her when she goes and see if she's just hanging her behind out of the box or if something else is going on. She's always had a problem w/dingleberries because she's a long hair but this is more than that. (The things I talk about. Honestly.) So, all in all, I'd say this is a good report. PT prayers at work!
