Please take her to a vet ASAP. Hard to know what to do to help her if you do not know what is wrong with her. A vet can make this evaluation and let you know what needs to be done.
Please get her to an emergency vet, now.
Get her some water at least, with an eyedropper in small amounts, and get her to the vet right away.
I agree with the posts of CML2014 and AnnieBrooke but this poor kitty
needs to be seen by a vet as soon as possible. An emergency vet would
probably be the best choice as that's what they handle " emergencies"
and this definitely qualifies. All animals need water and food and especially
water. Your kitty may be majorly dehydrated. This could account for her
stumbling around, but only a vet can diagnose what is going on with this
kitty. This sounds very serious. Don't delay. She needs urgent medical
care and needs to be seen by a vet to determine what is going on with
this kitty. Please keep us posted how this kitty is doing. Good luck. Eve
Could you please let us know how your kitty is doing? We worry too.
