I've had 4 cats: Sabrina, Samantha, Tac and Rudy. Bri and Sam died when I was young, and Tac had to be put down a few years ago...but Rudy is still around, though I hardly see him because he is always hiding. He is afraid of his own shadow (and the doorbell, and footsteps, and sudden movements - I think you get the picture).
When my stepdad moved in with us he brought a dog and I have never been a dog person...but Casey was a good first dog. He was astonishingly well-trained and obedient. He was affectionate to those he was familiar with, but when he was a puppy he lost one of his eyes and that made him sort of anti-social. He lived to be 18 and passed away in my stepdad's arms.
After that...we adopted this monster:
Bayley! When he was a puppy he was abused, and a rescue service took him in. He then bounced around from foster home to foster home, but always ended up back with the service because he was so badly behaved. We took him in when he was a little over a year old, and he was a terror. He had a radar for the most important thing in the room, and would choose to destroy that thing. It was hard, but we forgave him and kept him. Couldn't imagine my life without him. And gosh, if he isn't the cutest thing.
