At first I thought Mishi didn't purr, but it turns out he does. For a huge cat, he has the softest purr I have ever heard! I have to get my ear right next to his softest-fur-in-the-world to hear it, but he does purr. On the other hand, Mitzi has the loudest purr I have ever heard! It's so funny to hear this loud rumbling coming out of this little round cat.
