I grew up with a German Shepard/Collie mix names Sabre. But he wasn't a "pet" in my mind, he was my big brother (he was 3 years older than me and was my protector, friend, confidant and snuggle buddy). Sadly, he had to be put to sleep at 16. After that, mom said no more pets.
So the first actual pet I had was a baby bunny almost 20 years later. We bought her at a flea market for $8.00 and they actually put her in a paper bag to carry her home in. We named her Ceaser because we were told it was a male. When we took him/her to the vet the next day they said "ummm, no. You have a Cleopatra!". She just became known as "Bunny" after that. She lived in our double walking closet when we weren't there and had free run the house when we were. She was such a sweetie. Many mornings when I did not have to go to work early she would snuggle on my should while I petted her and sang "Catch a Falling Star". She would grind her teeth, snuggle up, fall asleep, and upon waking would promptly poop in my hair. Yep, routine didn't change regardless of the cats. She needed her quality time at least once a day.
Lord, I miss Bunny.
I rehomed her when I had to move and she had another 2 years of happy living. She passed at away at age 6 which I understand is not a bad age for Buns?
