We actually think she is being too lethargic so she is making the trip to the vet later today. While she normally sleeps a lot, she didn't even climb on anyone's shoulders yesterday which is definitely not like her!
Update: So they think she is just having a kitty cold. Phew! She's on suppliments (that hopefully will be yummy enough to eat) and that should help her get better soon and maybe even help her permanently squinty eye.
