I had a cat that did the same thing. He seemed to be ok other than the occasional marking. Long story short he did have a UTI.
I still blame myself for not taking him to the vets, right when i noticed him doing it. This was like 12 years ago. But he really did seem ok.As it turned out it was strain of bacteria, that turned toxic in his system. The vet did all he could but he passed inless than 2 days. I dont remember the fancy name for it, but i do know the vet said that sometimes in fixed cats it happens, but not that common. I will look and see if I can find his vet bill to see if the name of it is on there, its been so long but I may still have it.
Is you baby Fixed? You may want to have Her checked if she continues.
My baby did this for about a month or so, then one morning BAM,
he was really sick. It all happened so quick.
Not in any way saying this is the problem, and with everything goin on, it may very well be emotional.
I wish you well and will check back. Take care to all...
Just me...
