I have a silkie that is kept in her box during the day while I am at work and is out in the evening and all day on the weekends. I have noticed that lately, she'll walk into from the kitchen into the dining room and sit in one corner. Where ever you put her in the house, she will end up in that one corner. Also, I've noticed she is eating her regular food but won't touch treats anymore. And lastly, her chattering has increased alot. When she is out, roaming the house or sitting in the corner, she makes these cooing, clucky, squeaky sounds. Like a doot, doot, doooooot sound. So funny. Also, if you call her name, or the nickname my daughter gave her, she shakes her head. If anyone has anything to offer on any of this, please share.
