OH,what an oldie you have.I'm afraid Simba has never adapted being blind,if it's to do with the strokes he's had in the past i don't know.I have never changed any furniture around but he gets himself into a right state,he goes bashing into doors,furniture,and i'm surprised he hasn't knocked himself out.Sometimes i think am i being cruel keeping him going,i really don't know,it worries me so much.His teeth are rotten,his legs are weak and he needs carrying up and down the stairs
