When I was, I dunno maybe 12 or 13, I adopted a stray siamese cat (read: I found it outside and took it home) and named him the stupidest, longest pet name I could think of so his full name on thw vet file was Snowy Diamond Twinkle Marshmallow Fire. We just called him Snowfire for short; though he ended up with the nickname "damn cat" because he was a little shit and got into everything.
My favorite story about Snowfire was he took off for 2 whole years and then came back home like he never even left. IDK where he went, but if he was taken in by other people they left his collar and tags on and never contacted us.
