I had a cat named Mushy when I was growing up, it's Danish for Kitty. She got hit by a car.
Then I had Mr. Pudge, who was a Manx cat.
Then I had Petey, a cat, better known as Peteykins, or Pete Pete, among a lot of other names that were randomly made up. I lost my Peteykins this past March and he was almost 21 years old.
Currently, I have Buddy. Original. However, he was a homeless (not feral, he doesn't act feral at all, I think he was abandoned) cat that I fed for a year and then he showed up injured. So we got him fixed and took him in. I called him Buddy like 'friend' and when we brought him to the vet to be fixed I decided that was his name. So officially he is Buddy O'Malley (after Thomas O'Malley, the alley cat!

).
I had a dog as a teen named Callie but once she got her license and rabies tags her name quickly changed to Tink. I even changed her license name and at the vet, so it was official. Sometimes referred to Tinkerbell, Stinkerbelle, Stink Dog.
My friend has a dog and his name is Tosh or Toshi. I love that and him! My sister had a cat named Mr. Box after the Jack In the Box commercial where Jack was called Mr. Box.
