Cats can generally interfere with getting any human work done, ("pet me, Pet Me, PET ME!!"), but Pepper in particular can really be a perpetual problem when I'm trying to record voice work. (Yes, I used my pop filter while reading that sentence.) He's a perpetually happy cat, which means he's constantly purring when he's awake, and he seems to be allergic to cat hair, so he snores when he's asleep, which is most of the time. Pepper loves to eat, and he somehow finds a way to do so very loudly. Finally, I never knew cats could sing before I met him, but he loves to sing, loudly, to his favorite toys, (a chewed-up hair band and a long twisty-tie).
