Query: More like a question than a review

I've been thinking about getting one of these for my Umbrella cockatoo since currently he's taken to playing under the running water in the kitchen sink and doesn't really get anything wet other than his head and face. I was reading through the product information and the reviews for this to see if I could get a question answered and I haven't found an answer to it. So for those of you who have one of these, my question is this: At some point the suction cups are going to wear out and not stick to the wall very well. I really don't want my U2 to be perching on this and it fall off the shower wall with him on it. Is there any way to be able to change the suction cups and put new ones on when the old ones wear out?
