sorry for you're problems with senior kitty. what is worrying you..the dilated eyes and the crying, did you mean she started vomiting last night??...
All these signs don't sound good at all, I hope you did as spirit advised and called you're Vet or took her to some ER clinic by now?
Please keep us posted on her condition...and tell us more specifics about her condition so perhaps we can be of some help....but she really does need to see a Vet.
can you contact you're Vet?
does your vet have an emergency #? or is there an vet emergency room in your area? You must be so worried! Please let us know how you make out-it doesn't sound like she's doing great today!
