[Tamaki is silent for a few seconds while he thinks that over. He really doesn't have a concrete solution to a problem like that; he's never experienced something like it, so why would he have a solution? But he wants to help his friend so he tries to think of every possible solution.]
Maybe you can ask a friend to adopt Kaoru's ferret, but keep them as close as possible! You could take care of the other one for your friend and even try to keep it with you without Acumen knowing. If you do that Acumen can't say that you adopted them both because you didn't.
I would do it, but I can't adopt another pet... Ah, maybe Haruhi will be willing to do it!
