Let's see, throughout my entire life I've had the following pets. I don't count them if I released them into the wild after a week, like bunnies etc.
Golden retriever - parents brought him before or after I was born. Great dog, his name was Bandit. He died when our neighbors left out anti-freeze in a water dish.
Poe - Mom my cat adopted from the parking lot at a school. We had him for a year but he ran away.
Jupiter - Australian shepard we got in 94. Had him until 98 when we moved and he was an outside dog so the experience was traumatic for him so he ran away.
Elmo - Longest lived pet, had him for 15 years.
Lux - Golden retriever, still kicking. Brought her in 01.
Oscar - orange kitty, brought him in 2010 a month after Elmo passed.
Steve and Hermin - Two hermit crabs I had for a good 3 years.
Curtis - Huge corn snake my dad had, awesome pet. I can't remember if we gave him away or if he died. This was back in the mid 90s.
Prudence - Siamese fighting fish we had. Died after a year and we got Elmo.
