Hi,my cat has all of a sudden become very unwell,in december 06 she had an ingrown claw which was treated and ever since she has been fitter and healthier than ever.

Up until 2 weeks ago she started excessive sleeping and she seemed quite disorientated aswell,,she has lost a lot of weight and we took her to the vet who did a blood test and checked her.The test came back with nothing to show and he found nothing.
Her right eye also has a problem which occured after the vet visit,it started out with her squinting but now she has opened her eye it looks cloudy.
We took her to the vet again and he didnt really have an answer but gave her antibiotics and a booster to help her appitite.

What would and should we do next?

Thanks for any suggestions
