I hope it was a hairball... but I'm not quite sure. I found it on the middle of the floor last night and it seems to be her only indiscretion, so I'm going to give her the benefit of the doubt.
Vante is really flourishing. She's enjoying sleeping under the bed and almost always comes out the second we get in the room. She is eager to get out of the room but is only doing so under strict supervision.
One issue is that she doesn't like fans and hides when they are on. We have fans in almost every big room in our house, so we're going to slowly have to work through this issue.
She has seen her sisters, but still hasn't met them personally. For the most part all cats seem to be ok with the other. I'm hopeful.
