My cat has the first stages of cataracts and I did not notice till I noticed she chews on leaves. I often wonder why she was so skittish around people she does not know. I test her eye sight regularily and will monitor her pupil dilation in response to soft light in her eyes. I am also considering incorporating dry cannabis with soft cat food to see if her eyes swelling reduces , if I see her inner eye lids start to close I will know we are gaining some recovery. I think she has glaucoma cus her inner eyelids do not close. She also has slight fogging that makes me suspect cataracts. I love this cat so much she saved my life from a dark place I owe her some solid care! Any advice would be fantastic Namaste all!
