They really have that scary kitty side hop down pat now...and love to practice every day! I've been a bit concerned about Gracies left eye, (and PMd Meg). She had a huge chunk of kitty litter stuck on the eyeball two days ago, and she didn't let out a peep when I flushed it out under running water. It may be that that eye may need removing sooner rather than later. She is able to blink them, and I've been putting in a mild ointment daily to lubricate them more. Gabriel has the eyes disappearing, and Gracie's are huge. It's quite strange having two totally different kittens like this, in one litter. I'm guessing, but if they followed the sound of the ball, they were in perfect tune with their littermates who see! I think the bigger test is something silent when it moves. Maybe I'll try slowly moving the feather wand around and see if they follow that with their eyes. It's just near impossible to bring that out without all the big guys trying to kill and cart it away!
