Abbey has been lethargic all day and her third eyelid is showing. She's usually very playful and sweet. She hasn't eaten or drank anything today. I noticed that she's shaking, like quivering. I called my emergency vet and he asked me a bunch of questions and he said try and give her some wet food and if she ate it then it could probably wait until tomorrow. She acted interested, but then she didn't eat it. She just went into the litter box and looked like she was trying to use it, but then there was nothing in there. She has never in her whole kitty life since I've had her, slept all day. So now I'm waiting for the vet to call me back.
