So this morning Pixie wasn't opening her right eye properly and when she tried her third eyelid was half way across the eye but after a bit her eye seemed back to normal so we thought nothing of it, but she has been hiding upstairs all day and hasn't eaten since breakfast yesterday. Last night she was coughing a little but she has always had coughs and she's not coughing today. I also haven't seen her use the litter tray today which worries me too. she looked up at us earlier and her right eye reflected light back but the other didn't and after looking at her again my boyfriend says her right eye looks cloudy, I haven't been able to see because she keeps running away when I get close, no matter how slow I go. I'll be phoning the vet in the morning to see what they think but until then any ideas on what it could be and how worried I should be would be greatly appreciated.
