Cats in heat.

Or rather, semi-cats in heat, as they are still relatively young. But in related news - My kitty had kittens last night! Little tiger-kitties. Aww...wittle itty bitty baby puds.

But back to the main topic. Cats in heat, that is. They might be one of the most annoying things ever. They either roam around the house going "MeeeeooooOOOOOOOoooowwwWWW", or they go "MeooOOw, waHHhaaa, MeOOOooW, waaahhHHHaaaa, MeeeeEEoooW, WaaaHHaaaa."

Take your pick, and enter the house of maddening feline hormones.
