Christmas, Thanksgiving/our Wedding Anniversary, and a good snow storm.
3 pets I’ve had:
Oh, about a zillion, but three stand out – Brinks, a pit-boxer mix, a thirty-pound cat named Blitz, and Blazer, a pit/Greyhound mix. Yeah, I know. That one must have come with an instruction sheet.
And there you have it. Why not list your “3s” in the comments?
