Maybe take the bird to the lady's house & see if the cat shows an interest. I would also ask the lady if the cat is easily trained & how active she is. I would go for it. As I said in my previous post, I didn't even know about this subject. And nearly had a bird & cat. The budgie I had when my boys were little used to talk & fly around the room. I think we had my persian at the same time & there was no problems.
