There's a "holiday" or two for (what seems like) every day of the year. 

According to nationalcalendarday.com (the authority on these matters, I'm sure) April 30 has a lot to celebrate: It's National Bugs Bunny Day, National Raisin Day and National Oatmeal Cookie Day.

I feel like I know how to celebrate those (make some oatmeal raisin cookies and eat them while watching Looney Tunes, obviously), but another April 30 holiday makes how to participate clear in its name.

National Adopt a Shelter Pet Day is Saturday.

To help you celebrate, Pima Animal Care Center (4000 N. Silverbell Road) is offering free pet adoptions this weekend (Friday April 29 through Sunday May 1) on all pets over six months of age.

The fees typically cover the pet’s spay or neuter surgery, vaccinations, microchiping and a vet visit—all of which will still be included during this adoption weekend. A standard $16 licensing fee will apply to all adult dogs.

Enjoy your weekend of meeting your new best friend.
