I don't regard any of my pets as "Hobbies."
I do love to go fishing, camping, shooting at the range. I suppose all of these could be considered hobbies.
I also play music, specifically Bass Guitar and Guitar, in a Blues/Rock band. Not sure if this would be considered a hobby, as I sometimes get paid for services rendered. I do have a full time job, but Play music mainly 2 weekends a month.
