My cat has been prescribed Clomicalm in an attempt to stop her soiling outside of her tray. She has been on the tablets for about a week now, and they seem to be having a remarkably odd effect on her:
She sleeps in a box in the bedroom all the time, or on the windowsill, and doesn't want to leave the bedroom.
When she is not asleep, she is sitting bolt upright with staring eyes and very dilated pupils.
She is not interested in food or playing, strokes or anything.
I thought it was having some effect on the poo issue, but she performed outside of the box again tonight.
A bit of background as to how we got to this stage: We have already gone through Feliway (she pooped next to the diffuser), Zylkene (no effect), have ruled out UTIs (but vet put her on special urinary cat food in case there was a problem). She was not just pooping next to the box, but would also do it right next to her food, while she was being stroked, essentially, just where she happened to be at the time. The other cat finds this very distasteful, and shouts loudly at her when she does it (he was particularly unimpressed with the turd next to his food). She just gives him a "fuck you, mate" look, and stomps off.
I'm going to call the vet tomorrow, but does anyone know if these are normal side effects, and will they improve/will she get a bit more normal? Or do we need to try another drug?
