I think I was about five and it was this gorgeous maine coon cat I named Ariel.
She was an indoor/outdoor cat and one time she went out for a bit and just...never came back. My mother said she most likely either got hit by a car or the Asian people down the hill ate her (seems a bit racist I guess, but she said she had proof they were taking in strays and eating them...as a child, I never doubted her. I think it was just one of those neighborhood rumors though.).

I always figured she just got lost and was adopted by someone.

I had pets since the day I was born.
My first official pet that was 'mine' was a dead, frozen robin I found in the snow. I named him Stiff, and evening my parents would put him in the freezer because he would thaw out during the day while we were playing.

I was 2, and we got a dog and cat around the same time. Miss them both so much </3

Pretty much when I was born, a dog

we always had pets even before i was born we had dogs and cats and a horse

I guess as young as when I was born.
