Tilly has been very quiet and has had no appetite since she came back from our cabin Monday night. She was pretty normal walking around in the snow, and first I just thought she was tired out after 4 days at the Mountain, but she has gone outside and laid down in the snow at home, and seems disoriented. At 13, She is old, but just had a wellness check last week with no obvious problems. We have a vet appointment this afternoon, but I am concerned that something significant is going on. Please delete my accidental double post.
