Interesting stats, Moth, thanks for posting those.
Present pets:
I'm Sienna's at least second home. She was an owner turn-in at the shelter, but no information on why, or if that was her only previous owner. She was about a year old at the time.
Georgette and Claire, cats, I got as kittens from the shelter so first home. Claire is a failed foster.
Sidney, my parents' dog, came from a shelter with I think one previous home which was on a farm.
They also had three cats that they got from friends as kittens, two remain. One of the cats, Frankie, went to live with my brother briefly but didn't adjust very well, so she's back with my folks.
Childhood dogs:
Indy - GSD I got as a puppy from a breeder, and he was given to a couple after about 2 years (my parents' decision.) I still wonder about him. First, not only, home.
Lady - Golden Retriever puppy given to me at Christmas when I was either 4 or 5 (*great* idea, right?) We gave her to a family with older, sturdier children after a few months. First, not only, home.
Vanessa - Golden Retriever, my mom's dog. No idea how long my mom owned her, but she died of old age when I was a toddler. Maybe first, and last home.
Childhood cats:
Amy & Licorice - my aunt's cat's kittens that lived with me until we moved to an apartment and they were pried from my little arms and rehomed. First, but not only, home.
Kit - at a different apartment, he was either a stray or a neighborhood cat that liked our house better than his. Probably at least second home, but not his last. He went to live at my dad's office when we moved again, and ran away soon after that. I still wonder about him, too.
Tinkerbell aka Suki aka Socks - At yet another house (welcome to my childhood) she was the neighbors' cat, but decided our house was better so she became 1/2 our cat and 1/2 theirs...actually it was more like 1/3 ours, 1/3 theirs, and 1/3 another neighbor's, LOL. Not sure how to count her, she had 3 homes at the same time!
Loki - got him as a kitten, he lived with my stepdad before my mom married him (though he was my cat at the time.) Then he lived with all of us in house #...well, I stopped counting. He moved across the U.S. with us and lived out his life with my parents after I went away to college. First and only home.
Wow, my childhood pet history is depressing! Back then there wasn't a big stigma about rehoming, or at least not that I was aware of. Nobody ever told us we were horrible people for doing so, and I understand that life changes happen, and most people don't do their homework before getting a dog, and even if they do, they still don't always know what they're getting into. Though I understand, I was slightly traumatized by it as a child.
Needless to say, Sienna, George and Claire will be with me for life.
