Happy Birthday... kind of.

According to Alice's paperwork, today is her birthday. I love birthdays and would love to celebrate hers, but here's the catch: being a stray, the only paperwork we have is from the vet that saw her while she was in the shelter-- and because of that, we're pretty sure today was the day she lost her puppy.

Because it's all over her paperwork, we use today on anything where we have to list Alice's birthdate to keep things consistent. But since it may not actually be her birthday, and because there might be something not so happy associated with it, The Human Male and I are a little conflicted on how much we should celebrate it-- particularly since we also plan on celebrating her adoption day.

What dates do you celebrate for your pets? Birthdays? The day they came home? Both? Neither? Something else?
