What is "New Baby Syndrome?"
When I first adopted Biscuit at 1-2 months, I separated her from her last two siblings (I quickly decided to adopt them for a couple of other reasons, as well). The first night, Biscuit was very alone and sad. She mewed at all the corners of my room, searching, searching, calling to her siblings (I kept her and her food and litter box in my room for the first few months, I didn't want her to get lost or stuck in any non-kitty-proof rooms downstairs). My heart hurt so much, and I was sure I wanted her to have companions after that. ^_^
