Thanks everyone. Yes, my vet did mention glaucoma and she may have also mentioned retinal atrophy as well. She was so hard to catch last night and I knew that she wouldn't sit still so I grabbed my claw control bag and I put the velcro neck hold around her neck and I put her inside of it the best that I could. She's gotten so big that she's outgrown it. While giving her the eye drop she still wiggled and I don't even know how much of the eye drop I was able to get into her if any at all. I didn't want to give her another one. I just hope that tonight will go smoother. I wish that it was a thicker solution because then it would be a lot easier. I've already ordered the extra large claw control bag and hopefully all of my cats will be able to fit into it. So far so good with the new litterboxes. The one by the door was used the most. I haven't noticed any new pee accidents either.
