I did take Milukhu to the vet; the vet says healthwise, she is fine... nothing is wrong with her. (But, he didn't seem to be that thorough). Milukhu also got her annual shots. So far, she's eating good, (very good appetite), temper seems to be a bit better now, but the pooping problem still exists. She just won't go into the litter box to poo, but will go in to pee. And now, she always jump up to my loveseat to poo at the same spot. I used those solutions for getting rid of the odor- but she doesn't care, she doesn't even smell the spot she wants to go at, she'll jump up there and start to poo! A couple times I caught her and immediately picked her up and put her in the litter box, then she did it there. I had some newspaper on the loveseat and she end up pooing on it. I guess, better on the newspaper than my couch again... I even bought her own litter box- a brand new big litter box for herself! She peed in it, and that's it, no pooing. Now I have 4 litter boxes for 2 kitties. I don't know when she will learn to poo in the right place again.
Over the last few weeks, Bumpy seems to be getting along better with her. The can go to the kitchen to nipple in the same dish now... that was amazing, taking in consideration that Bumpy hissed at her for the first 2 weeks since Milukhu came home. I am glad at least they are not hissing as much as before. We'll see what happens next... I'll keep updating. Thanks.
