I haven't had that many pets in my life up untel now, but there's 4 of mine, my moms old ones and my friends....
Fluffy: My cat Dee-Dee's sister, one day when I was at school and my mom was shopping, she jumped up onto the counter and knocked over a coffee mug, it fell on her tail and cut it open, there was blood EVERYWHERE when my mom got home, that's not why she died, though, she got really sick after that and we had to give her away, I don't know if she's dead or not, but...
Hammy and Hamie: They were mine and my sisters hamsters, yeah, she took the name Hammy from me but tried to say she didn't by changing the way it was spelt. My hamster was 3 and hers was 2, mine died of old age and hers died from a really bad cold, I feel bad now because I rarely paid any attention to them..
Rex: I took him from my friend Irene's dad who kept him in the yard all day, even in the winter! They never took him for walks and he had no training. One day Irene and her sister, Ila, came to see him and he ran out the gate, we made them go and catch him but they said that they 'couldn't find him.' I don't know if he's dead or if somebody found him, though..
Peaches and Cream: My very first pets they were
only mine, I let my sister name them after an old rap group/rap song. My cat Neo got in and attacked one of them, I found out when I got home from school and cried for hours. The other one died because the water got too cold....
George: My moms old cat who thought he was a dog, he even cuddled up with her dogs sometimes! He died of old age when he was 18.
Tippy & Toasty: My moms 2 dogs, I think they were beagle mixes, they both live to be 14 and I'm not quite sure why they died, it could of been old age..
Fluffy [Number 2]: My best friends cat, she named it after mine, she ran away when they moved and got lost...
Trinity: My best friends other cat, I named my cat Neo and she named hers Trinity. [Their both people's names from The Matrix, used to be our favorite movie..] We thought Trinity was a girl until her mom took 'her' in to get fixed, and they told us that 'she' was a he.

He ran away when they moved and didn't come back..
