We have three cats, and soon fish!
Tails is Mr. Trouble. My friend with ferrets does not go through as much as we do with this bad boy! He has learned how to open drawers (so gets into the clothes, digs them all out, and sits in the drawers). He figured out that turning off the power switch that controls the wi-fi makes us come into his room (he cannot be out of the room because he randomly decided to start trying to kill our little female). He used to knock anything cylindrical on the floor, and I swear he would look RIGHT at us to say, "Hey, you watching?" while he did so! He sleeps on my stomach or curled up against my back.

Kirby believes in the philosophy of being a lover, not a fighter. He is 12 pounds, and he gets picked on my the 6 pound female. He usually just looks confused when she pounces on him, then wanders over for some consolatory petting. If there is an empty lap in the room, he needs to occupy it, even if he has never met the owner of said lap before in his life! He even likes dogs!
Scootaloo is the latest addition. Named for a spunky pony in the show My Little Pony: Friendship is Magic, she truly lives up to her name. She loves the new apartment, and she is convinced the carpet was put in solely for her. She rolls around on it or tears up and down the hallway (much better traction than the previous wooden floor!) most of the day. The rest of her day is spent pouncing on poor Kirby or trying to convince us she missed a meal. :P She refuses to share the multi-level cat tree you see in the picture with Kirby (even though there is plenty room for 3+ cats), so now every cat has his or her own tree. We're such suckers...
